Help! Anyone got pregnant on the mini pill?

Angel

I didn't know where else to put this, so I'm sorry if it's in the wrong place. Anyway, my last period that I had was about two months postpartum and lasted a week and ever since I've just spotted occasionally so I don't know when my period is supposed to be, I've just been marking approximately when it is based on the spotting I've had. My concern right now is that my husband and I screwed up because I forgot my pills (mini pills) on the 23rd and 24th and we had sex on the 25th and we didn't realize until after. I'm feeling flu like (achy), have a sinus headache, and am really really cold and chilled now and had ewcm on the 28th and light spotting today that I'm hoping isn't any sort of implantation spotting because we definitely don't need two under 2. Have any of you gotten pregnant from accidentally missing the mini pill?
