What is going on!!!

Chrissy

So we have been ttc for 6 months now, I’ve been using Glow & Ovia & OPK tests to track my ovulation. and for 6 months , both apps have ALWAYS got my ovulation date correct! But this month... I was ment to Ovulate on the 5th, tested every day for 6 days & they all came back negative. On Tuesday (the 14th) I had a pain in my left ovary all day, tested using my OPK test & it was positive! Now I am SO SO SO confused, why did I ovulate so late when every other month I have been on time! And AF was due on Sunday, so this now mean she’s not going to come because I ovulated so late!? So sorry this post is so long, but I’m going crazy!!!! Thanks ladies!xx
