I NEED OPINIONS!!!

So I had a MC the day after Christmas. Kind of messed my last cycle up. I USUALLY have a 25 day cycle that you can set ur watch by.... I have been checking OPKs since I finished period just because I was afraid my cycle was still going to be weird. Today is the FIRST day of my fertile window according to GLOW, but my opk is almost positive!!! We haven’t BD since Friday! I feel like I’ve lost my chance to get pregnant this month. We will BD tonight and tomorrow, but have any of y’all had this happen??
