OK I am kinda freaking out...It gets kind of TMI here...Me and my OH had sex and he did his thing in me...I used the bathroom right away and cleaned up and stuff...Laid down to watch tv...Like 10 minutes later I got the most painful BHC ever...It seemed to last forever and almost had me in tears...I couldnt even talk...Well I tried to roll over to see if I could alleviate the pain and I had a gush...So I freaked and jumped up and went to go to the restroom...I think it was just urine...I was still having the contraction even while going #1...Well I laid back down and the contraction finally ended...I then had several BHC's after that...I know it was more than 4 in an hour...But I hate hospitals and I don't want to go in...But I keep telling myself if I have even one more that painful I am going to go...The other BHC's were not painful at all...Just uncomfortable...So my questions are... 1. I have read that having sex and semen can aggravate the cervix...But I think I also read that the cervix has to be ripe and ready to go to cause actual contractions...But I am really confused about this and may be wrong...I am sure it was the semen or the sex or both that caused the contraction but should I still be worried about it? 2. I am worried about what can and cannot cause change in the cervix...I can't exactly word this question here...I guess what I am asking is,is it possible that maybe I am thinning out or effaced or dialating or something since the contraction was SO painful? Or do you have to have a lot of them to cause a change? 3. 2 days ago I was crampy all day but yesterday I was fine for the most part...Do you think this is linked? 4. I usually try to empty my bladder before having sex but this time I didn't...Maybe having sex on a full bladder caused all the pain? I am just really worried now and soooo confused...Please help!!
