I need major help! I think I'm pregnant! I hope I am, but I cant tell.?

Firstly, go and buy Taking Charge of You Fertilty by Toni Weschler. This is imo the best book for deciphering atypical charts. You see, you really need to start temperature charting to see what's going on with your hormones. That will also show if you are ovulating. It is possible that you are having implantation bleeding and just had a really short surge and missed it but it could equally be you aren't ovulating properly yet or have low progesterone and that's causing this spotting.
