I have a few concerns about mammogram and pregnancy

baby

Hello everyone,

I am very concerned about a mammogram I did last week, I did 2 pregnancy test and both negative! So I went ahead and did my breast biopsy and mammogram! So This Thursday I went ahead and took Another test, and to my surprise positive! So my last period was 8/14 and only lasted 2 days nd normally it’s 4-5 days , I have been feeling super tired and once in a while nauseous but on the week my period was due I had my mammogram which was on 9/10 test is negative! Now it’s a big fat positive. But my main concern is that damn mammogram some say it’s bad others say it’s not a big deal ! Can anyone give me any info ?
