Have unexplained infertility> hypothyroidism (controlled) TTC#2?

It's possible you ovulated early and will have a shorter cycle this month. Have you been tested for fertility issues? PCOS? Perhaps with the off period (you said not normal but didn't say if it was light, short, early, etc.) Is it possible you might have had implantation bleeding rather than your period and your multiple early +OPK are actually a sign of pregnancy? *Baby dust!*
