Quick stabbing pain in uterus?

Langie

So all week I’ve had small noticeable mild cramping on & off in my uterus area but last night I had this quick stabbing pain in my uterus that felt like lightning jolted around my whole uterus 😳 it kinda hurt and had me stood still for a second like woah . Been having bad lower back pain and super bloated!

According to the app I’m 13 dpo tomorrow. Anyone felt that quick stabbing feeling and got a BFP? Praying for my rainbow baby 😩🙏🏻🔥
