I was really positive I am ovulating but my Wondfo Ovulation strips say otherwise. Every month around the time of ovulation my uterus gets slightly tender/sore and I have very mild cramps. Ive had that for 2 days now and my O strips say im not ovulating.. If they are right why am I having these symptoms?? I was thinking maybe they happen right before ovulation instead of on ovulation like I thought?? But I always just assumed it was ovulation because its always near the middle of my cycle, this is the first month ive really tracked my ovulation. I am currently on calendar day 14 and I have 18 days until my next period. So im guessing any day now on the ovulation right?? My forecasted ovulation date is the 11th and my fertile days are the 7th-11th.
