Is it just me ???

My partner and I had sex last week and after he was done he told me it felt different since I got pregnant like it’s more tight and in a different angle . Well I was curious to know what he was talking about that I decided to examine myself with 2 fingers inside my vagina and come to find out it is different like I am hitting a wall or it’s lower now idk but I am wondering if this is common since I am just 7 weeks and my body is getting prepare to carry a baby ???
