Stomach really sore?

Kat

I’m 35 weeks and a few days. My stomach feels sore like I did sit ups for two days straight I can hardly move I went in to the doctor today and they did an ultrasound to make sure she was caught up because she was falling behind alittle and it hurt bad when she was doing the ultrasound. She’s very low (for them to see the top of her head They had to put the wand on the very top of my clit) witch I don’t know how low she’s supposed to be but I feel like that’s low but I’ve also been having period like cramps. Is this normal?
