It's scary when things change, bubs has a quiet day and you get big changes in CM.

The I have lots pieces of my plug from very early on in this pregnancy, although I am glad I haven't lost any in the last few weeks, but it has been the consistency of the greenish/yellowish stuff that you described earlier. I lost it with DD thoughout my pregnancy, but a grea thing is it can replenish andmy OB wants to be aware when I do lose it and how much, but has said to not get too concerned unless it is a few cm long and large pieces.

This pregnancy I also have a lot of extra CM that I didn't have with DD, my OB said I looked primed at 16 weeks so there is definitely a lot there, but my cervix lengths although shortened are still tighly closed

The extra discharge could be linked to your IBS, as everything is so close together in that area that a few rumbles can make a few things shift around IYKWIM.

I hope that bubs kicks up a storm for you in the next few days, and it is great that your MW is just a phone call away, but if you feel any other changes, and BH's increase in them cramps etc, please get to the WA at the WCH to be checked out if your MW can't come by, take care and thinking of you xxoo
