People’s menstrual cycles vary a lot, and they may be irregular even when they’re using birth control. If you have irregular periods, see your doctor to find out the cause.
Having unprotected sex during your fertile window can lead to pregnancy. However, sex itself does not delay your period.
1. Hormones
Hormones play a big role in regulating the menstrual cycle. The hypothalamus and hippocampus in the brain are responsible for sex hormone regulation. Diseases that affect these glands can cause irregular periods.
Estrogen Estrogen is a female sex hormone that helps with puberty, pregnancy and regulation of the menstrual cycle. It is also responsible for vaginal lubrication and tissue growth. Progesterone is another sex hormone that helps with ovulation and pregnancy. Testosterone is a male sex hormone that causes puberty, muscle mass growth, increases bone density and controls facial hair growth.
While orgasms do not delay a period directly, they can help relieve menstrual cramping and pain. This is due to the release of endorphins, which act as a natural pain reliever.
If you are unsure whether or not your missed period could be because of sex, it is best to visit a gynecologist. This can help identify the cause of the delay and recommend treatment options. Having a healthy diet, getting enough sleep and exercising regularly can also help regulate your hormone levels, which may also help with delaying a period.
2. Exercise
Generally, sex doesn’t delay periods (unless you get pregnant). However, it can make them come earlier or be more painful than usual. This is because sex causes a surge of hormones during the arousal phase that can affect your monthly cycle.
Similarly, excessive exercise can affect your hormonal balance and lead to irregular periods. This is particularly common in athletes and people who train for competitive sports. This can be because of the increased level of prolactin which can cause a delay in your period or because the body is trying to conserve nutrients for important functions like pregnancy and growth.
Additionally, certain forms of birth control can also impact your menstrual cycle. This is because these methods work by altering your hormone levels to prevent ovulation and thicken cervical mucus to make it harder for sperm to reach an egg. This is why it’s important to talk to your healthcare provider about any issues you may have with your period and the best method of birth control for you. This way, you can avoid any unnecessary changes in your hormonal balance.
3. Nutrition
While sex itself doesn’t delay periods, eating well and getting plenty of sleep can promote hormonal balance and may help regulate the menstrual cycle. Not eating enough, very strenuous exercise, illness, or using hormonal birth control methods may also affect the timing of your period. In addition, if you have sex during the final phase of your cycle (when womb lining thickens, an egg is released and progesterone levels rise) it can sometimes bring your period on earlier than expected if it results in orgasm. This is because orgasm increases blood flow to the uterus. Often spotting or light bleeding after sex is the start of your period.
4. Stress
If you are a woman who menstruates, there will likely be one or more times when your period is a day or two late. While pregnancy is a big reason for a missed period, there are also other reasons that your menstrual cycle can be off, including extreme stress. Having high levels of stress can cause your body to go into “fight or flight” mode and this can have an impact on the hormones that regulate your menstrual cycle. Stress can cause your body to produce cortisol, which in turn can impact the hypothalamus (which is in charge of hormonal regulation).
If you are under a lot of stress, it may be time to talk to a therapist or doctor to get some help managing your symptoms. Small variations in your menstrual cycle are normal, but if you have had unprotected sex or a fertile window has passed since you’ve had your last period, it’s a good idea to take a pregnancy test. If you find out that you are pregnant, it will be important to discuss birth control options with your doctor to prevent complications.
5. Pregnancy
Women’s periods can be irregular at the beginning of their menstrual cycle, but they typically become more regular as they age. Many things can affect your period, including hormonal birth control, exercise or diet restrictions, stress, thyroid imbalance and Polycystic Ovary Syndrome.
The only time sex can delay your period is if you are pregnant. This happens because pregnancy changes your hormonal levels, which prevents the endometrial lining from shedding. This can cause a missed period, along with early signs of pregnancy, like abdominal bloating and cramps, fatigue and sensitive boobs.
Pregnancy tests work by detecting the hormone human chorionic gonadotropin, or hCG, in your urine or blood. Typically, you will need to be at least a week past your missed period to get an accurate result. If you are not sure whether you are pregnant, talk to your doctor about a pregnancy test. Taking a pregnancy test too soon can give false negative results. If you have a positive result, be sure to follow up with your doctor. hCG levels decrease over the course of the first trimester.
