Chazen, ive asked every girl I know during their pregnancy to get those estrogens mentioned checked. Why? Because my MS wont stop progressing and ive read how many times pregnant women (not all) lose some MS symptoms untill a few months after birth when those levels go back to normal.
Estriol is the one I think. Ive pushed my neuro so many times but he's too old for new tricks. He even gave me trial results for a few meds and Estriol was one with this least side effects. It helped in the trial. I wont get into the story why Estriol isnt easily avail anymore (thanks Wyeth & FDA) but god id love to know if you do become pregnant how/if your symptoms change along with those levels. $30 each at my local lab.

btw..Rebif is made from Chinese hampster ovary cells. Ovary's where alot of that stuffs made no?
Asked my neuro if Rebif contained estrogens. He laughed at me. I still think there's a link.
