18 weeks and

Ahrrianna • I'm Ahrrianna & 28. Married 10 yrs. Have 4 beautiful kids on the way! IG: quinncharger15
I'm 18 weeks today and all day today I've been feeling like pressure in my lower abdomen like I guess where the baby would be coming out lol but anyways is it just cuz he's choosing to snuggle really low or could it be something else? Should I contact my doctor?
