Can pregnancy occur post sex, even after having two periods?

Question

Hello doctor,

I had unprotected sexual intercourse two months ago. Then I had my menstrual period after three days, and after that a month ago. I also gained almost 11 pounds after returning to my place. Is there any chance that I could be pregnant after having two regular periods?

Kindly advise.

Hello,

Welcome to icliniq.com.

I have read your query and understand your concern.

Based on the information provided, the chance of pregnancy from the sexual intercourse is extremely low, almost negligible. Here is the explanation:

Unprotected sexual intercourse occurred.
A menstrual period occurred shortly after.
Another regular menstrual period occurred later.

A true menstrual period occurs when the uterine lining sheds in the absence of pregnancy. Once pregnancy occurs and implantation takes place, menstrual periods usually stop. Therefore, having two normal menstrual periods after that sexual encounter strongly indicates that pregnancy has not occurred from that event. The weight gain of 11 pounds after traveling or relocating is more likely due to:

Changes in dietary habits.
Reduced physical activity.
Water retention or bloating.
Travel-related stress.
Changes in sleep patterns.
Hormonal fluctuations.

These are common reasons for sudden weight gain. However, for reassurance, a home urine pregnancy test can still be performed. Since more than 21 days have passed since the sexual intercourse, the result would be highly accurate.

After having two regular menstrual periods, pregnancy is highly unlikely. If the main concern is the recent weight gain, further evaluation can help determine whether it is related to bloating, hormonal changes, or lifestyle factors.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
