I just finished an hour swaying and leaning forward on my birthing ball and when I got up I started getting this really uncomfortable feeling very low in my bump. It's a mixture of heavy feeling, sharp pains and nausea. Could this mean the baby is engaged? I'm 36+1 weeks and don't think I've had BH so far, or if I have I've complitely missed them, so I'm not sure if this is them instead..
