I’m 33 weeks and for a few weeks now, it feels incredibly uncomfortable to lean back when sitting. It feels similar to lying on your back, a weird feeling of slight nausea, wooziness. I know that this can happen lying down due to compression of an artery or something like that, but does anyone else get it when just sitting? I’m ok if I sit up upright or forward, but if I lean back a bit I just start to feel crap!
