While spotting or bleeding after sexual intercourse is common, and orgasm can help ease menstrual cramps, there is no evidence that sex dramatically changes or delays periods. However, if your period is late you should take a pregnancy test.
Small variations in the length of your cycle are normal. But, sex can play havoc with your hormone levels and cause you to miss your fertile window leading to pregnancy.
1. Hormonal Imbalance
Women’s hormones fluctuate a lot, especially during puberty, pregnancy, and menopause. But sometimes these fluctuations cause hormonal imbalances that can lead to symptoms like fatigue, mood swings, weight gain, acne, and irregular periods.
If you experience any of these symptoms, talk to your doctor or gynecologist about it. They can perform tests to determine the underlying cause of your hormonal imbalance and recommend treatments like medications or other home remedies that may help with your symptoms.
Hormonal imbalances can also lead to conditions like polycystic ovary syndrome (PCOS) and endometriosis, which can contribute to irregular periods, infertility, and other health problems. If you have PCOS, your doctor may prescribe birth control pills or other hormones to help balance your hormone levels and regulate your menstrual cycle.
Hormonal imbalances can be caused by a number of things, including diet, stress, and certain medications. Changing your lifestyle and practicing healthy habits can help lower your stress levels, balance your hormones, and improve overall wellness. Acupuncture and herbal supplements can also be helpful in managing hormone imbalance during menstruation. However, it’s important to note that menstrual discomforts and other signs of a hormonal imbalance can be different for both men and women. So, it’s best to consult a medical professional to get the right treatment for you.
If you’re feeling extra stressed, your hormone levels may shift. This could cause your period to come early, be late or even not happen at all.
When we experience extreme stress, our body releases a surge of stress hormones called cortisol to help us cope with the situation and keep us safe (think: outrunning the imaginary lion, tiger or bear). This response can sometimes disrupt the delicate chain of hormonal processes that triggers ovulation and brings your period in. This is because your body wants to conserve energy to fight the threat, so it shuts down non-essential systems — like the ovaries — to avoid any unnecessary risk of pregnancy.
A few days of irregular periods is completely normal, especially if you’ve been through a lot of stress in your life. Some variation in your menstrual cycle length and phases is also common in people who are pregnant, using a hormonal birth control method or have a condition like polycystic ovary syndrome.
Protected sex isn’t likely to affect your period, but other factors such as illness, not eating enough, extreme exercise, having a low body weight or taking certain medications can also affect your menstrual cycle. It’s important to take a home pregnancy test or see your doctor as soon as you miss a period to make sure that you aren’t pregnant.
3. Hormonal Contraceptives
People who use hormonal contraceptives like the cyclic combination oral contraceptive pill (commonly referred to as “the pill”) often have monthly bleeding that mimics their periods. This is because the pill uses oestrogen and progestogen to disrupt the fluctuating hormone signals that would normally trigger ovulation. People who use the progestogen-only MiniPill or long-acting birth control like Mirena IUDs may also experience lighter periods.
While sex won’t delay your period on its own, having unprotected sex during a fertile window of your cycle can lead to pregnancy. You can check to see if you’re pregnant by taking a home pregnancy test.
If you’re using a reversible form of birth control and don’t get a positive result, try again in 1-2 weeks. Pregnancy tests work by detecting a specific level of human chorionic gonadotropin in your blood or urine, and the results can be less accurate if you take a test too early.
There are a lot of things that can affect your menstrual cycle, including lifestyle, stress, certain health conditions, and pregnancy. Small variations in your menstrual cycle and irregularities in your bleeding are normal, but if you’re worried talk to your doctor. They’ll be able to help you find the best treatment for you. Track your menstrual cycle in a period app and keep an eye out for any changes that could signal that you’re not feeling well.
For most women, the period ship sails right on through the first trimester of pregnancy. And even if you do get your period during this time, it’s not the same thing as a regular menstrual cycle, but rather the shedding of the uterine lining to make room for a fertilized egg.
You can still fall pregnant during a period, but it’s less likely to happen if you use birth control. One reason is that a woman’s hormones are in a different rhythm than they usually are, and their levels of the progesterone hCG rise to prepare for ovulation. The most fertile window is usually around the time of ovulation, and having sex at that point can lead to pregnancy.
During pregnancy, it’s also possible to have bleeding that looks like a period, but it’s usually much lighter and only lasts for a few days. This is called implantation bleeding and it occurs when an egg is fertilized by sperm. Spotting during pregnancy that doesn’t last for a few days or is very heavy could indicate a serious problem, such as a preterm or term labor or placental abruption.
If you experience this, contact your doctor immediately. They’ll want to do an ultrasound to check the health of your baby and assess any potential complications. This is particularly important if you’re already having symptoms of a possible placenta previa or abruption.
