Conception after AF.. any stories?

My

fiancé and I had sex multiple times every day of my AF(he cam inside me every day) I’ve been fine up until this past Sunday. My period came on around the right time but it was much lighter, and way too short. My breasts are beyond sore, nauseous, my cravings are through the roof, my sense of smell is high and I’ve had period like cramps for two days right after my assumed period. I plan to test today but does anyone have a similar story? And ended up pregnant.
