I have been continuously spotting since 5 weeks pregnant. The spotting progressively got worst and I started to get light bleeding at 8 weeks. The bleeding was brown and would come and go so I wasn't too worried. But since week seven I experienced my pregnancy symptoms getting better. Now at the end of 8 weeks I barely have any symptoms. I took a pregnancy test and the line came up immediately but it was light and didn't darken how it used to. I'm worried that I'm miscarrying
