I've been having major shooting cervical pain for several nights, and only sporadically before that. I lost what apparently was my mucus plug about 2 weeks ago so gradual changes have definitely been going on, I'm a good 3-4cm right now but still slightly posterior and less than 50% effaced. I'm on forced reduced activity to hopefully keep anything from happening before 37 weeks. I have maybe 2 or 3 contractions over night but that's it. I think its a combination of stress and a very low baby putting lots of pressure on my cervix. Everything has been happening at night so I have a feeling I'm gearing up for prodromal labor (yuck).
