6 Reasons Your Period Could Be Late Besides Being Pregnant

Whether you get your period every 28 days like clockwork or have a flow that prefers to come and go as it pleases, having a period go MIA often feels like cause for alarm. Your mind runs wild with thoughts of pregnancy tests and ultrasounds and watching your baby graduate college - an imaginary life that you’ve created and nurtured and helped grow all because that little bit of blood you were hoping to find this morning didn’t make it’s appearance. Whether pregnancy right now is your goal or you’re holding off temporarily or forever, a fetus in utero is certainly not the only cause of a period gone rogue. Here are 6 reasons, besides being pregnant, that your period could be late.

1. Stress

If you’ve been running yourself ragged at work or dealing with other stressors, especially traumatic ones, your period could be late. This is called hypothalamic amenorrhea. “The hypothalamus is the center of the brain and controls reproduction. It produces a hormone that signals the production of other hormones needed for ovulation,” according to Shady Grove Fertility. So, if you’ve been stressed about something - big or small - do your best to find some time for relaxation. If you’ve experienced a traumatic situation, you should call your doctor and seek a professional opinion.

2. Being sick

The amazing things your body does are all intertwined on some level. When one system isn’t working as well as it should, the others are affected, too. It’s like a game of survival - which bodily process is the most important right now? If you have a common cold, the flu, or some other type of illness, your menstrual cycle is likely the first to be shut down in order to get the rest of your body back up to speed.

3. Weight fluctuations

Say hello to your hypothalamus again (the center in the brain that controls reproductive hormones, like estrogen). When you experience extreme fluctuations in your weight, the amount of estrogen released can impact whether you get your period or not. If you lose a lot of weight quickly, your body won’t produce enough estrogen. Too much weight gain and your body will have too much estrogen. Either way, this could be a reason your period is late.

4. Change in your schedule

Minor changes in your schedule aren’t going to have an impact on your menstrual cycle but intense ones, like switching to the night shift or having jet lag from traveling across the world (you jetsetter, you!), can. The good news is that it’s temporary. Once your body acclimates to your new schedule, your periods should resume as normal. If they don’t, it’s worth calling your doctor about.

5. Hormonal Imbalance

Hormones, of course, play a large role in your menstrual cycle. They determine the heaviness, the length, and even whether your period comes at all. If your hormones are out of whack, you may not menstruate. One cause could be PCOS. Another could be endometriosis. If you suspect this is the case, call your doctor. They’ll be able to put you on a path to help regulate symptoms.

6. Your birth control

Yes, even if you don’t skip the sugar pills, your birth control could be editing your menstrual cycle. Whether you have an IUD, get Depo shots, or are on the pill, the hormonal changes caused by birth control can sometimes eliminate or lessen your period. While this can sometimes be a welcome side effect, it’s good to know that it’s actually the cause of a late or nonexistent period.

If you think you’re pregnant, it’s always a good idea to take a test. Otherwise, talk to your doctor about your late period - they can provide valuable insight and ease your mind.  If you are looking for sustainable, stress free period then check out our range of period products.

Hi Nike,

Being sick can absolutely affect your cycle and flow. The amazing things your body does are all intertwined on some level. When one system isn’t working as well as it should, the others are affected, too. It’s like a game of survival – which bodily process is the most important right now? If you have a common cold, the flu, or some other type of illness, your menstrual cycle is likely the first to be shut down in order to get the rest of your body back up to speed.

Taking medication can also influence the menstrual cycle and cause periods to be late. Hormones regulate the menstrual cycle, and many things can affect your hormone function and balance and cause it to get off balance.

If the period doesn’t return until next month, if you think you might be pregnant or generally if you are worried, I would recommend consulting a doctor. Please keep in mind that we are no medical professionals and therefore cannot make a remote diagnosis. Only a medical professional can make the necessary examinations.

Hi Mwiche!
Hi Favour!

Sorry to hear your period is late! I totally understand that it causes stress and insecurity.

Many reasons might delay your period, such as stress, hormonal imbalance, or lifestyle changes like a new schedule. Hormones regulate the menstrual cycle, and many things can affect your hormone function and balance.

Delayed periods can always be an indication of pregnancy. Please note that the easiest way to find out if you are pregnant is with an at-home pregnancy test.

The morning after pill isn’t a contraceptive method and there is therefore a chance of both pregnancy and STD. The pill contains a huge amount of hormones which can cause changes in the menstrual cycle for even a few months after use. Please refer to the instruction leaflet of the morning after pill for information on its possible effects on the period and a possible delay and/or ask your doctor or in the pharmacy.

If the period doesn’t return until next month, if you think you might be pregnant or generally if you are worried, we recommend consulting a doctor. Please keep in mind that we are no medical professionals and therefore cannot make a remote diagnosis. Only a medical professional can make the necessary examinations.

My name is mwiche and I am 19 years old.in june I once suffered from urinary tract infection which I think caused my period to come early on the 12 of august that too for just 4 day without heavy flow.Then I had unprotected sex the 19 of august on the 8 th day of my menstrual cycle but took the morning after pill on hour 30 mins later after the sex. Today is the 4th of September and I still haven’t seen my period do you think I’m pregnant.though my breast are full and heavy and soft I also feel a sharp small pain in my waist when I get up.

Hi Rashmi,
sorry to hear your period is late. Many reasons might delay your period, such as stress, hormonal imbalance, or lifestyle changes like a new schedule. Being sick and taking some medication may also influence and mess up with your menstrual cycle. Hormones regulate the menstrual cycle, and many things can affect your hormone function and balance.
Especially when you are young and started with your period it is common that the period is irregular. It may not come for several weeks. Or on the contrary, it may also happen that you just had your period and it is coming again quickly. Your body and hormones need to find their balance first and during this phase, which may take some time, it is common for the period to be irregular. This means it can be irregular when it comes to the length of the menstrual cycle, but also when it comes to the length and intensity of the period itself.
If the period doesn’t return until next month, if you think you might be pregnant or generally if you are worried, I would recommend consulting a doctor. Please keep in mind that we are no medical professionals and therefore cannot make a remote diagnosis. Only a medical professional can make the necessary examinations.

Hello, I’m 17 years old. This is my first time experiencing delayed period. Last month September I had my period but this month, I’m still waiting. I don’t have a boyfriend and im not sexually active. But I always take caffeine in the morning. According to my research, caffeine affects the menstruation and I’ve been stressing a lot and it affects my academic performance. November is near and I’m not having it. What should I do?
