Does anyone else do this? This is my 2nd pregnancy my first ended in miscarriage at 12 weeks. In 4 weeks 2 days right now and I've know since 2 weeks and 6 days. ( blood test that was unrelated to pregnancy but they called me and told me small levels was found and I needed to come back in I did and confirmed it.) I keep takeing them like crazy I ended up takeing 24 with my first and I've done 13 of these and today I'm haveing my 3rd blood test!
