Should I contact my doctor ???

My legs started to get super achy/tingly feeling & my feet have started to swell today. But just about 45 mins ago my stomach started getting rock solid & hasn’t let up at all. My BP was 116/66 this morning at my doctors. Which I know is normal (my BP is normally around 90-100/50-60 range). I’ve been drinking plenty of water & eat fairly healthy. So I’m kinda confused why out of no where I’ve started to feel weird. I’m 33-34 weeks pregnant by the way. Thanks ladies.
