Ftm. Contractions?

Hi ladies💕 I am 18 and a FTM. I am 36 weeks (37 this week) I am on bed rest due to high blood pressure. My doctor things it’s preeclampsia starting so we had bloodwork done Monday and I go back tomorrow morning for another blood pressure check and to see what’s next. I’m laying in bed and having a sharp crampish pain that last a bit but not super long. I haven’t had Braxton Hicks or any contractions before so I don’t know if that’s what I’m feeling? Just trying to get some input. Tia
