Sex & 2nd trimester

Soooooo I noticed that lately every time my boyfriend and I have sex my vagina gets really puffy and sore after I orgasm and it feels like a UTI after it settles down and goes back to normal it's itchy but that's the only UTI symptom I have is itchiness and it's not all day long it's only when he touches me so I'm wondering if I should go get this checked for a possible UTI or if it's just because I'm almost at the end of my 2nd trimester which I highly doubt is the case. I'm pretty sure it's a slight case of UTI but just wanted a second opinion since my insurance is currently canceled :( help me please
