What CD were you on when you started the synarel, and what day are you now? I started synarel on CD21 of the previous cycle to my stim cycle, and my period came about 10 days after starting it, on CD31, which was pretty normal for my cycles. (That was the last 'normal' thing that happened!) I had headaches, no cramps, but I understand some ladies get crampy, too. If you're on a similar schedule, you period would be due in a few days anyway, wouldn't it?

I'm with MummaSue, give your clinic nurses a ring today, and see what they have to say. Don't go for days torturing yourself with worry, there's enough stress in this process without stressing about things can can probably be easily explained and understood.

Re the acupuncture, I'm afraid if the ladies who have responded here don't know, you'll have to post it as a specific thread elsewhere (the AC forum, or in general conception, maybe?) or introduce your self in the AC chat thread and ask the ladies there.
