Hey Dr I was just wanting to know, my fiance’

Patient: Hey Dr. I was just wanting to know, my fiance’ and I did an in home insemination on the 1st April, the day her menstrual ended. A few days after that she was having some symptoms of pregnancy, everything besides swollen/tender breasts and vomiting. She has taken tests after tests of ovulation and pregnancy and they all say negative. She keeps having these sharp pains in her stomach, the lower, side, and middle. Could she perhaps be pregnant and the tests be wrong? She was bleeding like a normal menstrual Thursday evening and it stopped today. Her “regular” menstrual was to start today though. Can you give some advice/help?
