Help?

I'm 37 weeks 2 days today and for the last 2 weeks every night I constantly wake up at night and turn over and over because if I stay sleeping on my right side my right leg will start hurting alot and then when I turn to my left the same will happen. Today I woke up with ALOT of pain on my right side starting from my hip to my toes. I dont know if maybe it's because of my weight since I've never been over 110 and no I'm at 126 or if i should go get checked 😞
