HELP AND ADVISE PLEAS

Hello so I am 37 weeks and yesterday around 11 pm I started getting really sharp pain on right side of uterus and couldn't even stand and I was crying but then ended up falling asleep at 130 and then today i was super achy and started crying- i felt pms-y lol and then at 11 pm again I started getting pain again and now im in bed and cramping again but on the left side and it's not as painful as yesterday but I don't wanna move or I'll start hurting and I keep getting little twinges around my rectum like pressure and then it goes away... I've not felt like this at all my whole pregnancy so Idk what to do I've just been relaxing when I start to hurt, maybe I this early labor or something? ? any answers help thank u!
