So I posted on here the other day and had been testing every day but looked like getting lighter. I didn’t even bother testing yesterday and had officially given up ready to wait for an early AF. But... today at work had what felt like ovulation pain for a good few hours exactly how I feel it usually. I got home 6/7 hours later and did an opk, it’s dark but not a surge so guessing if I had tested last night I possibly might have got it then. I usually ovulate CD 17/18 so this is really late!
