Hi everyone! I did an OPK last cycle and believe I ovulated Jul 23 (smiley face appeared that stayed on screen for 48 hours) I'm 23 DPO and haven taken 3 pregnancy tests since Saturday, all of which have been BFN! My periods over a week late. Anyone think there's even a smallllllll chance I could still be pregnant?! Or maybe I'm just late. TTC for baby #1 for over a year now, so discouraging!! Any advice would help!!!
