I would take the prednisone and I speak from experience. During a previous pregnancy I started a bad flare around 11 weeks> It took me a week to figure it out because we happened to have a stomach virus going through the house and the prenatal vitamins made the stool so dark I did not immediately notice the blood. I saw my OB and Gastro and we upped my colazal. I was offered Prednisone at the time but was scared to take it. It took about
10 days for the Colazal to work, but it did get things under control. However, when I went in for my appointment at 17 weeks we found that the baby had apparently struggled and had died a few days before. The equivalent of an autopsy was done including about
30 different blood tests and no known cause or link was found except my flare. The blood loss had caused me to be anemic(which caused my OB great concern). To this day the doctors still don't blame the flare, but both doctors and a perinatalogist I have since consulted have all stressed that getting the flare under control is far more important than
the medication risks. As the host for your little one, the stress your body experiences can definetely affect the baby. At the time I was offered pred and declined, my doctor went over the statistics of how pred has been used in pregnancy for years and he considered safe and that the flare was much more harmful. Well I hate pred, having taken it before and took a wait and see approach. I don't want to scare or worry you in any way(it is the last thing you need), but I wish that someone could have kicked me at the time and said take the prednisone ( I respond very quickly to it). It may have not made any difference in the outcome but I will never know. I was so careful about what I ate drank took etc. that pregnancy and was scared of the meds(esp. pred), but my research since the loss has convinced me that the flare risk is much worse and if we ever have a child again and I experience a flare, I would be very aggressive about getting it under control.
