18dpo, multiple positives since 11dpo, now brown blood

Jessika

I’m 18dpo and I had multiple positives since 11dpo. Yesterday I took a test and the line was barely visible. Today I woke up and I have brown discharge. I’ve had multiple MC in the past and now I’m nervous. This would put me at 4w2d and I feel like it might be too early to ask my doctor for help.
