HELP! I’m freaking out! I thought I got a positive opk on Friday but then yesterday I had some weird spotting so on a whim I took a pregnancy test just now... there is definitely a second line on the pregnancy test and the opk is positive. I had a miscarriage and D&C 5 weeks ago. Is it possible my cycle was all screwed up and I’m pregnant again? Could this be a false positive? These tests are easy@home brand. What do y’all think? I’m seriously freaking out right now. ?
