is anyone feeling really really nauseous ?? 4 days until due date

What symptoms did everyone have going in to labour ?? Iv got 4 days until my due date and I feel SOOOOOO sick I literally feel like I'm holding the vom in even though I know I'm not actually going to be sick. I have increased watery discharge I haven't seen anything that I would think is my plug .. I feel like a lot of pressure down stairs like almost as if my insides are trying to fall out .. I'm having no contractions and no waters breaking etc i just feel like shit now just want it to be over so I can feel like my body is healthy again
