Advice?

Abbie • Love my family! Little girl named Rose and a baby boy named Azerith and a little girl due Feb. 9th gonna be named Zelda.

This is my second pregnancy and Im having very bad side cramping pains im 6 weeks and 7 days. I never had this in my first pregnancy. Is this just tightening for my uterus or? It hurts when it spikes up. No bleeding nothing like that. So im not freaking out or anything, I just never had this before? If you think it's something different please tell me.
