Weird, maybe TMI, question...

So, I am 34w4d pregnant and the past two times my SO and I have had sex I have felt VERY swollen down there. The first time I was so swollen we couldn't even do it. This is the first time this has happened my whole pregnancy and I was just wondering if this has happened to anyone else? And maybe what is causing it?
