Please Help BFP

About a week ago, my doctor sent me for a mammogram and ultrasound after feeling a lump in my breast.

Thankfully it was nothing. However when i was at the breast clinic they asked if i was preggo and i said no. I even called my dr office because they had taken urine 2 days earlier and they said it was negative. My period was due today and didnt show up. On a whim i took a PG test and its positive!

Now i am terrified that the mammo hurt my baby!!!! I have already had 3 miscarriages this year!!!!

Anyone have a mammo or similar and the baby be ok?
