Been trying to conceive just started But

Been trying for a baby with my husband but i am now bleeding during the process the first 4 days of trying was fine then 3 days later we tried again and i am bleeding during sex only …. So we took a break for 3 more days tried again and bleeding during it so had to stop .. didn’t want to stop trying but also don’t want to bleed is this normal? I don’t get my period until another 11 - 12 days and it wasn’t my period it’s only during sex then it stops….. but i am getting light cramping …..

going to take a break till i can see my doctor
