Hi,
Welcome to the ehealthforum and I am really glad to help you out.
As you had sexual intercourse during the unsafe period, the possibility of pregnancy is definitely there.
You can confirm the pregnancy without waiting for your next periods by doing a serum beta HCG test.
This can be done around 10 days after the ovulation. In case, you miss your periods, thatâll confirm the presence of pregnancy.
Meanwhile, you can consult a physician to look for any other cause of the pains which youâre going through. I sincerely hope that helps. Take care.
