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.

Hi, Julitta! Morning after pills are loaded with hormones, and hormonal imbalances will typically affect your cycle. A morning after pill can caused cycle changes for a few months. If you’re feeling concerned it’s best to discuss the situation with your doctor. :)

Hi, Ujjwal! If you’re concerned about pregnancy we recommend taking an at home pregnancy test. To prevent pregnancy you must use protection such as a condom, IUD, or birth control pills. You can discuss your options with your partner and doctors to find the best protection for you. :)

Hi Lynette, I had unprotected sex on march 30 and april 5th but my bf didn’t cum in me. I’ve been very sad and stressed this whole month. My uncle passed away on the 1st, i’ve been stressing over school + boys lol. my period tracker predicted my period to come on last thursday and never came. but i have a lil cramping / stomach pain & bowel movements been very active lol. two days ago i saw a lil pink discharge but my flow never started. I don’t have money or a way to get a pregnancy test so i have been doing diy test and they would come out negative. but i’m very confused and scared. i really hope i’m not pregnant, what do you think?

Hi, so I had my period on the 4th -7th of March. I made out with my boyfriend on the 20th of March. He actually didn’t penetrate me because I’m still a virgin, but he cummed on me. The problem now is I’m was expecting my period on the 2nd of April but till date no period but I still get my normal cramp that comes before period and boobs full with nipples pain and this time around I feel like throwing up. Am I pregnant?

Louisa April 14, 2020

I had evacuation on 2nd Feb and i didn’t see my period since then i fear i am pregnant again. I had sex 20th/21st of march and i immediately took levonorgestrel pills after sex. A week ago i feel cold, feverish and felt like throwing up i went to see the doctor, told me i had PID which i took injection and pills for by his prescription. And i have treated it twice between March and Early this month. But i get this urge to vomit although not strong. I complaint and he gave me a deworming pill. Which i took. Still having the vomiting urge. I took a pregnancy test which turns negative. But am getting worried. I want to take another test.

Praise April 14, 2020

I was hospitalized from January 31, 2020 to February 5,2020 due to bacterial pneumonia. I used to take Dostinex and Duphaston but from February till now, April , I don’t have my period and so I stop my Duphaston Due to absence of bleeding . Dostinex I didn’t take also as I have to see my endocrinologist every 3 months but due to current situation , COVID -19 , I ran out of medicine. What must be the reason of absence of menstruation ?

Aida April 14, 2020

Hi komal! If you’re concerned about pregnancy we recommend taking an at-home pregnancy test. :)
