Ohh sweet, hope you had a good sleep last night and are feeling better today? You could be having side effects from the crinone (I am guessing you're on crinone??) - I had AWFUL side effects from that stuff and will never take it again... You could also be dehydrated, have you had plenty to drink? Try warm water or weak herbal teas if you can handle it. If you're going for a fresh transfer you really need to stay as hydrated as possible. If you're still feeling terrible today, I would call the nurses Big XO.

As for side effects on pessaries - nothing compared to crinone. I am only on one per day, but have absolutely no side effects, and had quite severe side effects from crinone.
