I have regular 28 day cycles. I’ve never tracked the exact day I ovulate but I always get that sticky discharge and light cramping on when side which I always took as a sign that I was ovulating. This is usually around day 13-14. I had unprotected sex on day 7 of my cycle. Took a plan b (I’m a smidge above the bmi cut off) and today, day 23 of my cycle, I have spotting.

How concerned do I need to be for implantation bleeding vs just the hormone dump that is a plan b causing some spotting? Would implantation take a whole 10 days to happen (assuming worst case that the egg was fertilized on day 13 of my cycle??)
