Yesterday for about 5 hours I felt dizzy and light headed and every time I stood up or walked I felt like I was going to faint and fall down. Thankfully that passed with laying down for a while... but today the baby feels like he's really really low, like sitting on my cervix, and it feels like baby Mason is putting pressure on my pelvic area. I'm only 19 weeks and 3 days. I'm not bleeding or anything, I just feel wobbly and very uncomfortable. Any suggestions?
