Mrs. • Finally have our babies. R.I.P Kimara Jeffers. Welcome 2 handsome boys Allan and Kayden Jeffers. 👧🏾👼🏾👶🏾👶🏾👦🏾
My AF started on June 22nd. On the  3rd day (6/24) I'm taking clomid from June 24-28. I should be ovulated between July 3rd and 8th said the Clomid calculate. 
But my Glow said something different. It said I'll be ovulating on July 13. I don't get it.
