Took a plan b.. help!!

So as you can see I had unprotected sex on the 12th and my predicted ovulation day was the very next day, the 13th. My boyfriend usually pulls out but for some reason he didn’t that day, so an hour later he left to go get me a plan b. I took the plan b and did some research, apparently if you are already ovulating.. plan be is pointless to take. Later on the same day I took it, I went to the bathroom and wiped a ton of stretchy clear cm.. I was indeed very fertile the day I took a plan b. Apparently getting pregnant even after taking a plan b, is pretty common. I’ve got 2 days until my period is supposed to arrive. Starting last week, I’ve had constant mild cramping.. my boobs are so sore. They feel so incredibly heavy after I take my bra off. Two nights ago, I kept getting dizzy spells which never happens. I never cramp a week before my period, I usually start cramping within 3 days before my period. And usually my period begins with me wiping old brown blood but I’ve been wiping nothing for the past few hours and every once in a while I will wipe very light pink as pictured. I’m just tripping out because I took it while ovulating and also because apparently so many women get pregnant after plan b. What do you ladies think? And how many of you have gotten pregnant even after taking the plan b?
