Hi! I'm at FTM here and 30 weeks pregnant. For the past hour or so I've been feeling a weird rumbling, rhythmic twitching feeling in my lower right abdomen. I'm pretty sure it's where my placenta is as I have a low placenta. Does anyone know what it could be? The baby is kicking so I presume he's ok in there but I'm feeling really freaked out by this weird bubbling/twitching and why it won't go away. Scared it's something to do with blood flow to the placenta?! Any help appreciated! Thanks
