15 +5 lower abdomen discomfort

Lauren

On and off just today I have this pulling feeling, discomfort in my low abdomen/pelvic area. Yesterday and today I was also having a pulling feeling in my belly button as if someone was inside and pulling my belly button inward. Hard to explain. It doesnt hurt it's just uncomfortable. Im not sure if it's the pregnancy or because my belly is growing and I'm already a plus size woman. Just want to make sure its normal.
