This is very intresting for me, i read on this forum about MS patients having fewer flares while pregnant, especially in the last three months of pregnancy. this is apparently true of all autoimune diseases. i talked to my mom and dad ( both gynocologies) and they said that they had seen this themselves. but they were unsusre why, like rick they discussed the increase in blood, changes in the immune system, and hormonal changes. We found on this forum a paper on an new study that they were doing on MS patient and the drug trimestra, we found the active ingredient to be estirol, and since it is a drug that has no side effects (as little as any drug can have we decided to give it a try. i have been on it for 3 weeks, and it has been the best three weeks since i got sick. i know it is too early to say anything but i have some hope. the only problem was that i went off LDN to take this drug and i coudn't walk anymore, if i stood up for more than 5 min or walked for more than 100 meters I would feel like shit, cold sweats, malaise, dizzy, i think other people with CFS have this (Orthostatic intolerance?) and i had always been so happy that i was spared... but so far i am happy with my new drug!
