The screen shot below is my calendar. I had sex the whole week of Valentine's Day. Not to conceive, but it's Valentine's day so why not. I didn't realize that is was also the week that my Glow predicted my ovulation week. Well, I started today, but I still have 4-5 more days then I should. Could it be implantation or just AF decided to join me early this month? Any thoughts and comments would be very much appreciated.
