so I'm freaking out a bit. Friday I was throwing up. Saturday my boobs started leaking, and I went to the bathroom and my underwear had a wet spot too. I've been crampy lately. and I'm not sure if I've just had more discharge or if parts of my mucous plug is falling out. when I sit down it seriously feels like so much pressure on my lower stomach/vagina. I'm 34 weeks and have a doctor appt tomorrow. all my appts I've been measuring ahead but have been told he's just gonna be big. and I'm just overly freaking out or should this be something to worry about.
