7+ weeks pregnant and just had some brown discharge

Taylor
I am 7w2d pregnant and when I just wiped after going to the bathroom I noticed some brown discharge. This is my second child and I didn't experience this with my first. I know spotting is normal in the very beginning with implantation but is it normal at 7weeks to have brown discharge? I'm feeling a little nervous and I don't go back to the doctors until May 10th
