Brown discharge?

Tara

Hello! Almost 7 weeks pregnant here with my second baby. I haven’t been experiencing anything out if the usual. Slight cramps, tons of nausea, sore breast and really sleepy. This morning I noticed when I went peepee that I had a brown discharge in the toilet and on my toilet paper. Light brown, no red blood. I don’t remember this happening the first time around. Is this a normal experience?

Thanks!
