So I'm 18 weeks with my second, I've felt movement for a while now, but I'm not sure if I've felt anything for 3 days. I kept waking up last nyt with a bit of pain, av gt a constant ache and feel sick. Rly not sure what I shud do? There's been a couple of time I've thought was tht the baby but I'm not 100% sure. It was a wriggle bum last week and kept me awake from movement
