Lower right side pain

A

So I’m 15 weeks pregnant and I’ve been having a sharp/tight pain on my lower right side since last night and I don’t know if it’s my uterus stretching or because I have a sub chorionic hemorrhage.

I’m not sure if sch is supposed to hurt or if it’s even on my right side. But I’ve had this pain before and I usually get it at night but it’s always gone by morning.

I did workout yesterday which might have triggered it.

I’ve called my Dr office and left a message for the nurse.

Should I go to the er or wait?

Anyone had this before?
