First Time Mom Concerns

Yessenia • 1st baby boy Alexander Grayson Soto 👶🍼❤
Im currently 30 weeks pregnant my husband has been cumming in me every time we have sex since the first day we found out we were pregnant . I recently was reading on here that a mans cum softens your cervix and makes you go sooner to delivery . I'm a first time mom so all this worries me. Recently my doctor told me my baby was showing to be a premature baby . Does anyone think it has to do with my husband cumming in me ?
