Brown discharge?

Abby

I just found out I’m pregnant and I’m 7weeks 2days. For the past week or so I have had light brown discharge. It’s been on and off. it isn’t heavy at all it’s only there when I wipe. I have looked it up a lot and I have already had two ultrasound right after I found out I was pregnant due to the fact that I had a miscarriage in December. If anyone has experienced this before and has any suggestions. Please let me know I’m going to call my doctor Monday. Pleas and thank you.
