But I'm a little confused. Let me start by saying i do have pcos. I'm only 25, I have one child already so I know I can conceive what I'm questioning is..the use of opks I just recently started using them this cycle to assist in getting pregnant asap only because I do have regular periods and I know I should be ovulating..I'm on 1500 mg daily of metformin anyways i started testing on Friday which would have been CD 10 or 11 it was negative I then got a positive on Saturday, Sunday A super dark positive on Monday and now today its positive yet again just not as dark...I have pics. Is this ok? Or is something wrong. I'm very confused
