Uncomfortable having sex

Is it just me or when I got pregnant, my vagina feels much smaller than it was pre pregnancy? I'm 10.5 weeks and it's felt like this probably since week four. It feels tighter and shorter if that makes sense. Even my husband said he can feel it while being intimate and he says it feels "swollen". It isn't unbearable pain but just when we begin to get intimate but also during where I feel he hits my cervix hard and then after I'm sore. What gives? Anyone else having this issue? It's killing my love life with my husband!
