My partner had her last period on 22nd October. We got intimate on 3rd November. We used protection however it broke when it was near her anus. There wasn't a penetration at all (she is a virgin) and there was no ejaculation I am sure. After two days, she started feeling severe headaches and doctor found out that her BP was very low due to cold. She took 2 pregnancy test today and both were negative. However she is feeling severe headaches and sometimes vomiting. Would like to mention that the doctor has given some strong Amoxycilin tablets for her cold. She is taking too much stress .Can there be any pregnancy issue?
