pregnancy. i had unprotected sex with my partner on 4th august and got my regular periods by 27th august. but after this i missed my cycle for september. my cycle is 29 days regular cycle. now i did pregnancy test twice and it came out to be negative. doctor has prescribed regrestrone 5mg for 5 days. can there be any chances of pregnancy still? iam worried. i have pain and uneasiness in my abdomen.
