Cramping very low

Annelise • 24. Married. I have a 2 year old and 1 year old sons.
I am 11weeks 5days. I have finally been able to eat an slowly getting my energy back. But now I am worried. It's uncomfortable to sick down. I have a really weird pain very low on my pelvis. I'm so close to being out of my first trimester an I don't want to stress. Any advice? My husband told me if it gets worse we should go to the hospital
