Pregnant with breast lump

Hi everyone.

I'm 25 years old and I'm currently 13 weeks pregnant with my second little girl. I did IVF to conceive this time around.

While I was waiting to find out if the IVF worked I found a small lump in my left breast. It felt to be about the size of a pea, well defined, deep in the breast, hard/rubbery, and only slightly mobile. I had a sinking feeling right away because the lump didn't feel obviously benign to me as an RN.

Fast forward to my 12th week of pregnancy where I had my OB try to feel the lump. She couldn't find it without my help and said she would have missed had I not pointed it out. She scheduled me for an ultrasound, which was last Wednesday.

The tech at the breast center had a hard time finding it as well and had the radiologist come in the watch to be sure that there was even something there. Turns out that there is 1.2 cm hypoechoic lobulated region, which is bigger than I expected.

The radiologist said it didn't look "overly suspicious". He ultimately decided on doing a biopsy because he said with me being pregnant it was more likely to change in the coming months and it would make sense to just be sure and not worry down the road. He also said if we didn't biopsy we'd have to follow up every3-6 months. He really didn't seem all that worried though.

I felt pretty confidant that things would be ok until my OB called me that night saying that she'd received the report of a BI-RADS 4 suspicious mass. She made sure I had my biopsy scheduled.

So for the past few days I've basically done all the research I can on breast cancer during pregnancy. I'm kind of a paranoid person so I already feel somewhat convinced that it will be cancer. I've just been feeling so scared in anxious to the point that I'm sick. My biopsy will be tomorrow and can take anywhere from 24 hours to 7 days for results which is basically like torture!

Just looking for any support/advice on how to make it through these next few days. Or anyone else going through a similar thing?
