I had unprotected sex day before ovulation and now its a day or two after ovulation and i have a sharp mild pain in my lower abdomen, what is it ?

Pain after ovulation: If ovulation occurred later than you thought, and the follicle ruptures later, the pain can be due to the rupture of a follicle (ovarian cyst). Implantation of a fertilized egg can also cause lower abdominal pain, so if your period is delayed, wait a week and obtain a serum HCG test to be certain about pregnancy.

Pregnancy test: If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine,
