Ok so my hubs and I dtd on November 11th (first day of fertile window) 12th, and 13th this month. According to glow I ovulated yesterday (16th) I never have any ewcm anytime of the month this is normal for me I suppose ...today and yesterday I have been having slight cramps in my ovary regions alternating sides...almost like period cramps, I am wondering what this is from? Ovulation pain, early implantation cramps, ovarian cysts? Another question is when do implantation cramps occur: or when did yours if your remember?
