Sex ?

So Just want to double check that Im really just Overreacting haha Im currently 6 months Pregnant And Im Single so I havent had Much sex since I found out I was Pregnant its only been like twice since well 6 months ago, Anyways I had sex and Afterwards there was slight spotting... Should I be worried or is it just cause it had been awhile for me and he was.... well.... above Average ?

Please no judgment a girls got needs haha
