Sex while pregnant

So, this is definitely more personal and uncomfortable.I’m 17 weeks pregnant and I just got over a bad UTI while being pregnant so it’s been a while since my husband and I had sex. Today we went to try and it was like he was pushing on my bladder, making me have to pee. I couldn’t enjoy sex with him since all I could think about was emptying my bladder. I ran to the bathroom and couldn’t stop trickling. Then I noticed My vagina muscles seemed swollen and larger than normal down there. Is this normal. This is my first pregnancy and this was a terrible experience. I feel horrible I can’t have sex with my husband.
