so first of all im a male but am asking for my fiancé (26F) we had sex for the first time a couple weeks ago and couple days after the sex she started having a nausea and stomach pain and we thought its pregnancy symptoms but in the 10-14 days after the sex she had a pregnancy test and it was negative and the stomach pain stayed the same , then after a couple days she had her period (and its like 2-1.5 week earlier) and coronavirus at the same time now she is having a abdominal pain and heavy period bleeding and she wont go to see a doctor because she is still afraid its pregnancy or maybe the doctor will know she had sex ( my country is religious so having sex before marriage is a taboo)

(she is not in a birth control)

so i have no idea what to do with her and i dont know if its okey to have this symptoms after the first sex im confused and i dont know what to do
