Pains?

So I’ve been having pains in my vag, for the past 3 days.

(I also posted about not having ANY discharge for a week or so when I was constantly having it the whole times of pregnancy)

I’m 29 weeks, almost 30 on Tuesday. I have an ultrasound Wednesday. But it feels like a lot of pressure on my vag like when I was it hurts and I have to walk around for a minute for it to go away. 🙃 I work 6 days a week, sometimes 7. 5-7 hour shifts. Sometimes on my feet a lot. Sometimes sitting a lot. I’m not sure if it’s something I need to call the dr about or just wait until my ultrasound Wednesday and then my appointment next Monday on the 30th??
