I've read so much about First Response giving false positives! I don't know what to think I would really appreciate it if someone could clear this up so if I have 3 days on the go of  faint pink positives then If I was to start Af that would be a chemical pregnancy?? Are people getting faint positives before AF having a chemical pregnancy and then blasting the brand of test..... I don't know when I was pregnant with my other two a pink line was a positive full stop no matter how light darker?? Xxx
