Hoping some OPK experts can help me... It's my first time using them, and I'm TTC after miscarrying. So I'm not exactly sure when I'll O because I don't know if my cycles will be similar to what they were before. ANYway..... I started taking OPKs on Monday:

Monday 9pm- Negative (seemed close, but not quite as dark as control)
Tuesday FMU- Positive
Tuesday 9pm- Negative (lighter than Mon night)
Weds FMU (5:30a)- Positive
Weds 9:30a- Positive
Weds 12:30p- Negative

What's going on?? I'm reading lots of places now not to use FMU, but the directions with the OPK said to (target up&up brand). Has anyone else used FMU successfully, or should I only test in afternoon/ evening? Am I getting false positives?

I don't think it's leftover hcg from the miscarriage because I tested with a FRER yesterday and got a stark white BFN. Right now I'm 15 days post mc. I KNOW this is why Dr's say to wait one cycle, but I did a lot of research and DH and I decided to try.

If anyone can shed some light on using these OPKs, I would be VERY thankful!!!!! I'm going crazy over here trying to figure it out. TIA :):)
