Yesterday, I took a very long walk around town and ever since then I've been having pain and my underwear magically become wet randomly and when it does it smells like cum and a sweet smell. Last night I started having side pain, pelvic pain, abdominal pain and very strong back pain.. I ended up falling asleep but I kept waking up in the middle of the night with sharp menstrual and pelvic pain, I just woke up and I'm having a little bit more painful cramps and they are really hurting on my sides. I went to the bathroom and my underwear are moist from where they are trying to dry I guess during the night my underwear was wet again and now they are trying to dry but it's still wet enough I could feel them wet and cold. I smelt them to see if it was just pee but it's definitely not pee, it smells like a strong sweet cum smell (again). My back pain is still there and my side pain is unbearable. Now I'm having pelvic pain and when I get up to walk my cervix starts to ace and hurt with lots of pressure on it (as it feels) I wish I could go back to sleep but the pains are hurting enough to where I can't sleep.. the pain can ease down randomly but would come back quickly within a few minutes sometimes seconds. What could this be?

Walking. I went into labor at 36 weeks and it was less than 5 hours long.

Not sure if it actually help me or not but I didn't start having real contractions until I started using my yoga ball.
