Aspen • 21 ♊️ diabetic💉 fur babies 🐕🐹🐈 Army wife 06.01.18💪🏼 Lennyx Mitchel 2.17.19💙🤱

So I’m 36wks 4d and I’ve been having mild cramps in my lower abdomen... like right on top of my vagina with some pressure all day on and off.. usually like once every hour or two.. it literally makes me feel like i have to poop but i never go poop. I have an NST later today so I’ll bring it up to my doctor but i was just wondering if any of y’all would know what this is.. if i should be worried. I’m due to be induced on Tuesday..
