Pressure/carrying low

Natasha

I'm 13 +1 with my 2nd baby and for the last few days, I've had a lot of pressure/crampy feeling down really low. It feels like this baby is sat right on my cervix and bladder, It's super uncomfortable and I always carried so high with my first so it feels strange to me. I guess I just didn't expect to feel like this so early in my pregnancy, is it because it's my 2nd? Does anyone else feel this?
