4w3d and Burning Sensation After Sex

My husband and I had sex for the first time yesterday morning since finding out I was pregnant (yayyyy!). It did not burn during and felt plenty wet, but after when I got up to go in and pee it burned! It lasted for about 5-10 minutes max then went away. Was fine and then this morning there's just kind of like a weird feeling. Doesn't burn but doesn't feel "normal" either. I've had a UTI before and it doesn't really feel like that, at least not yet. Thoughts?
