Poor you, have you tried any natural supplements such as probiotics, omega 3 oils, etc? I have very mild flares compared to others on this forum so I haven't yet treated with meds. I do find that I can't eat potatoes when I am flaring, so I substitute with salad for my meals. I also find that eating fresh, crushed garlic really eases my flares.
As for fertility and pred, I am way past the baby stage, lol but there are others that have had children and are planning families so they will be able to help you more.
Dx: UC Proctitis 2006
Meds: None so far. Garlic works to ease flares. My GI laughed when I told him and said it was just coincidence.
Diet: Regular fresh garlic, Biobest yogurt daily, Omega 3 supplements, very limited junk food, carbs and processed food, low fat diet. Lots of fresh fruit and veggies (limited potatoes).
Added: tumeric and probiotics.
