(TMI) bf thinks he’s hitting something during sex?

Valerie G. • 19 & engaged. First baby, expecting a girl 🎀

Anyone else had this happen? 35 weeks. We both are sure he’s not hitting the baby’s head but might be my cervix? We haven’t had sex for a week and we just did tonight but we stopped because it was weird. Never happened before so I’m not sure if that’s what he’s feeling. I feel a little different down there when we had sex she’s so low that it feels like there is an end while we dtd, so maybe I’m dilated? I will have my doctor check me my next appointment. Before we had sex tonight I’ve been hurting real bad for the past month with terrible pinching pain down at my cervix. It just now started to feel different when we did that
