NEED ADVICE PLEASE! 😩

So I’m 40+2 weeks pregnant. I had the sweep 2 days ago...now yesterday, I was ok-nesting and everything but then it got to 5pm last night (it’s now 7:30 the next morning) and i started to feel really faint and dizzy.

So 7:30pm came - I had a bath, got into bed and had serious period cramps - slept through them but couldn’t sleep till about 2 because it was so painful.

5am this morning came - I’ve lost some of my plug before but OMG I used half a loo roll and blocked my toilet wiping this thing away! I’ve now still got really bad cramps and they’re travelling to my back now too...any advice on what’s happening?!
