Hi!
Do you have a specialist managing your care? You have a complicated case. You might end up with octuplets if you are not in the care of an expert. (Most of us don't want them)
I would think that your doctor could prescibe something stronger for the pain, just ask! and you will need to watch your weight gain very carefully. If you start gaining a lot of weight it means that you are retaining a lot of fluid and that can be life threatening, so call, or go to the hospital.
If you are not working with a board certified reproductive endocrinologist, you should consult with one before your next cycle. If you do get pregnant on this cycle, be very careful too! In fact, your doctor should have told you to avoid intercourse!

thank you so much for your advice!! yes, i am working with some fantastic doctors who are monitoring me very closely. And since i dont intend on having octuplets, we were advised to only have protected sex. ALSO... i have gained about 6 lbs, and cant quite tell if that's normal or not. I'm 5'3" and normally weight 110 lbs, so is 6 lbs something i should be concerned about?!? thanks so much!!
