Spotting during sex

Rachel
So I had a baby almost 2 years ago. I had to have an emergency c-section. During the c-section the doctors accidentally lacerated my cervix. They stitched me up and all was well. When I recently went to the gyno she said the laceration on my cervix healed and looks good. 
So, whenever I have sex, and when it goes deep, I tend to spot during sex. It's a very lightly spotting but it happens during sex every time. Is this normal? It didn't start happening until after I had my baby.
