Ok girls, I am going to purchase ovulation sticks tomorrow to try and track my ovulation. I have never done this before. Our first pregnancy was totally unexpected but so welcomed. Unfortunately, we lost our handsome boy at 18.5W on Memorial Day due to PPROM. I just started AF on Sunday for the first time. I was reading about the ovulation sticks, it sounds like I am suppose to start testing on day 5 of my period, does this sound right? Day 5 would be tomorrow so just wanting some input on this before I start. Thank you!
