Thanks Bugsmum. No, I have to wait it out until my US followed by OB appointment, both on Fri morning. But I have found out progesterone levels can be affected by stress (and I have had some un-pregnancy related stress of late). So now I am feeling even more guilty.

The clinic told me it is not so much the level, and that it can fluctuate, but that there have been some significant drops. They got in touch with my Ob (I have not seen him yet) and he does not want me to increase my pessaries.

Hold on bubba...
