Weird question 🤔

My cycle length is 28 days , I had sex all days of my period with my hubby , i’m and i’m getting light migraines, coughing , and I peed on my self (TMI) sorry.... also had some right pelvic pain right now , & i’m only on CD 8 I googled and it said some one can end up pregnant within the next day or next 3 days . Has anyone ever had something like this or had sex on there period and ended up pregnant... I need to know . I’ve been wanting a baby for a while and it’s been so difficult for me
