All pregnancies are different, you will probably start contracting more, cramping more, loose yoir mucus plug, possibly start dialating. All these things can be signs of labor coming, but it could still also be weeks away. Unfortunatlu there is no way to really know when that day will come.
I am on my second pregnancy and this one is different then my first. So all pregnancys r different cuz I feel like I'm back in the first trimester and I'm 33 weeks the nausea is really upsetting.
I dont know but ill bump you up because it is a really good question and id like to know too :)
Ill threw out my pregnancy so far i was never physically sick (puky) ive felt like i would be but never was. Now im 31 weeks and if i dont take the medication the dr gave me, im sick every single morning! Just want to make sure its not an early sign of labour or something. Boys are hard to carry in the family and my mom lost two baby boys very late in her prgnancy so im a little on edge.
