I’ve been testing for the past three days because Glow has predicted my ovulation week to start yesterday. I’ve been testing with clear blue digital, the kind where it’s either a circle or a smiley. Well Thursday and Fridays I’ve got all circles which means there was no LH surge. I forgot to test yesterday morning due to us being so busy so last night I tested and I got my smiley. I tested twice to be sure and both were smileys so we BD last night. Well I tested this morning just to see if I was still ovulating and I got a circle which means no LH surge. Did I ovulate last night and it only happen in one day? I thought you were suppose to ovulate 12-36 hours after you got the smiley? Just kind of confused me since I’ve gotten all negatives up until last night and got the positive last night and negative this morning so it looks to me like I ovulated last night for only a few hours?
