Lower stomach pain after peeing

This has never happened to me so idk what this could be. I’ve never had a UTI before so maybe that could be it? I just woke up from an accidental nap (8pm to midnight) and I had to pee but not super bad. I peed, and then while doing my night routine I started to get bad stomach pains. Like sharp stabbing pains and it also felt like I could feel them somewhere in my lady bits (maybe urethra, not sure). But it was bad, enough to hunch over and say ow over and over again. I’m about 23 weeks. Since I’ve never had one before, I can’t be positive that’s what it is. My pee hasn’t been cloudy but it does smell unpleasant— even with all the water I drink on a daily basis. Should I MyChart my obgyn or do I have to go through with the walk-in (which I hate) thanks for advice!
