Almost had it

Last month I tried the ovulation chart. my period came one week late when I was a regular pms and we'll, I'll chop it up into a chemical pregnancy. So here I am, round two. It says my chances are high and I we tried everyday and I'm into day four. In the past I tried but not as hard as I am now. But now I'm having ovulation cramps. With having my period late, AI was unsure if it can measure my days accurate. But it seems as though my body is releasing and egg. Wish me luck as I am educating myself. He wants the baby and I'm going for the ride. Hello baby number three.
