alright mommas so question, I was laying down watching TV and I felt a weird pop feeling against my pubic bone like baby made a sudden movement there, which I've felt before but never a pop feeling. and ever since then I've been having bad period like cramps, the ones that make you feel like you constantly have to poop. which I did but I'm feeling no relief. it doesn't come and go so I don't think it's contractions. any advice? kinda nervous about this
