AF, just come. I know you're coming, so just come! Not 100% sure when I ovulated but I had a dark OPK on 17th and I took another one on the 22nd and it was light. Predicted ovulation was 18th. The 2 times I've done OPKs my luteal phase has been 13 days, even though my cycles were different lengths.... but 13 days ago would've been the 22nd. Oh I don't know. I'm not expecting to be pregnant. I've taken loads of tests now. All negative IC. I know some people think it's gross, but I do cervix check quite alot. I'm not sure where it's meant to be but it's sooooo high and there's no blood. Nothing. Just come if you're coming because I'm starting to symptom spot!! I'm fed up of getting excited and then just coming a few days late.
