15 weeks pregnant and have so much pressure, pain, cramping in my hips, and uterus area. My first born is only 6 months old. Could it be that it’s just because they are so close in age?

My body is hurting! Ugh! Any suggestions? I hate that it’s the weekend or else I’d call the doctor! My doctor did tell my I may feel like my uterus is falling out especially because babies are so close together but I hurt all over😬
