Yesterday was CD13 and last night my nipples were sore. I could of been imagining it, I had to press them with the palm of my hand to feel it. This morning my nipples aren't sore. I don't usually get sore nipples as an ovulation sign - well I don't really get any signs I'm ovulating! My periods are quite irregular since the birth of my daughter in 8/2017. Could there be a chance I ovulated yesterday/ovulating today? I had unprotected sex last night, so hoping to conceive! Tia x
