Weird 23 week symptoms

The last few days when I’m sitting down I get a random light tingling in my vagina. It doesn’t hurt and isn’t even uncomfortable it’s just weird. Also when I walk sometimes it feels like my pubic bone is rubbing together. It’s just driving me crazy that I don’t know what’s going on. I’ve also been having crazy amount of discharge and a weak bladder but I’ve been having that for weeks. Does anyone know what these symptoms are or what’s causing them? Gotta love the weird things pregnancy does to your body 🙄
