EVERY single time I come home from work, I have rather strong BH. Its a reminder that I pushed myself a little too hard... when I get home and lay on my left side, take some deep breaths, and hydrate myself, they always go away. This is also my third baby and I find the BH are much stronger than with the other kids (I didn't have any at all with baby #1).
My cervix is also soft. After a birth or two, it will never be completely "closed." Keep in mind that there is an external and internal OS to the cervix and even if the outer os is slightly open, the internal os should be closed tight. If you lose a lot of mucous or have other strange discharge (bleeding, etc) please call your healthcare provider. As soon as you begin contracting, lay down on your left side and drink tons of water. If you have rhythmic ctx for an hour and they don't stop when you rest and hydrate, I would definitely call your provider.
Don't be anxious, but also... don't take chances with preterm labor! :)
