Will having sex before menstruation delay menstruation? What are the reasons for delayed menstruation?

Generally speaking, when women have sex, they are very concerned about whether having sex before menstruation will affect the arrival of menstruation. So, will having sex before menstruation delay menstruation?

Will having sex before menstruation delay menstruation?

Sexual intercourse before menstruation will not cause delayed menstruation. Delayed menstruation is generally related to mental stress, environmental changes, etc.

Having sex a few days before your period will not delay your period because it is not during your ovulation period. The ovulation day is around the 14th day of the next menstruation. The ovulation period is the time combined of the 5 days before and 4 days after the ovulation day. It is easy to get pregnant if you have sex during the ovulation period.

Reasons for delayed menstruation:

1. Pregnancy

After the menstruation is delayed for 10 days, you can go to the hospital for a urine pregnancy test. If the result is positive, you are very likely pregnant. There are also other symptoms of pregnancy, such as chills, dizziness, fatigue, nausea, vomiting, etc.

2. Medication

Taking progestin-containing drugs, such as progesterone, emergency contraceptive pills, etc., can prolong the luteal phase and cause delayed menstruation. Newer generation gastrokinetic drugs may also cause delayed menstruation.

3. Caused by surgery

For example, uterine surgery may cause adhesions in the uterine cavity or cervix, which may prevent menstrual blood from being discharged, thereby delaying menstruation.

4. Endocrine disorders

Obesity, excessive dieting, irregular living habits, premature ovarian failure, polycystic ovary syndrome, etc. can all cause endocrine disorders in women and lead to delayed menstruation.
