So, even after I had my daughter I still felt some type of movement in my stomach. I googled it (yeah I did lol) & it said it's normal. Today,my lower back hurt like a sharp pain for a while, randomly. Recently my stomach has been being kinda weird & different 😏 .Maybe because I had a period (still tryna figure them out again) & just stopped a few days ago. I was on BC but just stopped taking them. Just want to know what y'all think? I will be taking a test soon before I start taking my BC again.
