Reasons why my period is late
"Your menstrual cycle is your check engine light," says Kirsten Karchmer, founder of menstrual wellness company Brazen and TikTok period expert. "It's basically your feedback tool for how your body is responding to how you're caring for it."
With that in mind, here are a few possible reasons for a skipped cycle:
1. COVID vaccines
For the past year and a half, we've been wondering, "Can the COVID vaccine delay your period?" It certainly can.
According to Dr. Sandra El Hajj, vaccines ask the immune system to work harder than normal, which could in turn affect menstruation. Your shot could possibly result in heavier flows, shorter cycles or no cycles at all.
"The data are pretty clear that while both getting Covid and getting vaccinated disrupts menstrual cycles, but very short term," Karchmer says. "There's no long-term impact, but there have been pretty significant short-term impacts."
Typically, women and people who menstruate get back on track after one or two cycles following their dosage.
2. Secondary amenorrhea
According to The American College of Obstetricians and Gynecologists, secondary amenorrhea occurs when someone who menstruates does not get their period for three months or more.
Approximately 1 in 25 women who are not pregnant, breastfeeding or going through menopause are likely to experience secondary amenorrhea, which is caused by a number of reasons: extreme weight loss, issues with thyroid glands and chronic medical conditions, to name just a few.
As previously mentioned, the only way to get to the root of the problem is with help from a professional.
"Stress is the most underrated [reason]," Karchmer insists.
Just look at what stress does to the body: it results in illness, causes brain fog, decreases libido—the list goes on. It's no surprise that Aunt Flo is unpredictable when your stress levels are through the roof.
4. Polycystic ovary syndrome (PCOS)
PCOS is a metabolic condition that impacts your ability to use sugar, and you'll need to regulate its impact with a regular exercise routine and stress-relievers.
Per HealthLine, PCOS causes the production of more male hormones than normal, which can, in turn, stop ovulation from taking place. Symptoms include facial hair growth, mood swings and possibly infertility issues.
5. New medication or birth control
According to HealthLine, going on and off birth control can cause changes in your menstrual cycle. Additionally, blood thinners, antidepressants and steroids, among other medications, are also capable of doing the same.
Yes, there is too much of a good thing. Case in point: overexercising. Hitting the elliptical too hard and increasing those gym visits might negatively impact your period.
"You need resources to make hormones, and when women are overexercising, their resources become depleted," Karchmer says. "They're using a lot of their resources from the foods that they eat to build muscle and to provide energy while they're training. Those resources get devoid away from making hormones, which can delay your period."
Regardless of what's happening down below, it's crucial to prioritize your gynecological health.
"When in doubt, always check with your doctor," Karchmer insists. "You won't ever regret being overly cautious, even if you want to try a fully natural approach to any of these problems [above]."
The best way to ensure that you're getting the care you desire, according to Karchmer, is to find an OBG/YN with the same values.
'We have to retrain the way women and people with periods think about their cycles and their health," she adds. "We have to stop just tolerating all types of crazy things happening with our cycles."
