I've been having sharp pains all day and they feel like they are right inside my vagina, I think I've read it described as like sitting on a knitting needle. I've also been getting tightenings which aren't painful but are uncomfortable and get very hard. I lost part of my plug today as well, just a small part though this morning. Any ideas if this could be the start of labour or just normal as I'm 33 weeks and have already had complications with my waters leaking since 22 weeks and on bedrest, I am allowed to do a little more now I'm further on and everything has been stable with the fluid levels though. The baby is about 5lb 2 as of Thursday when I had another growth scan. What do you think?
