Originally, Glow predicted me to ovulate on the 17th... then yesterday morning I got a solid smiley on CB and a positive on opk. Glow moved my predicted ovulation day to the 15th (today). I took an opk this morning, and it was negative, so Glow moved my ovulation day to yesterday!!! We didn’t BD on the 13th because we were trying “every other day until a positive” instead of BDing every day like we have in the past! So confused!! Any thoughts? First month temping and first month using regular opks. I have only used CB digital in the past.
