You'll be safe on Imuran. Many pregnancies have been done on Imuran. I've received affirmation from several top GIs about that, as it was one of my worries too as it's still on my list of "possible" drugs.
As for the iron tablets, who put you on those? Couple of things. One, make sure you are taking a GOOD prenatal vitamin. It should have enough iron in it and your OB/GYN should be checking your blood levels frequently to make sure you are okay with iron. If your iron levels drop, then they might put you on an iron pill. It was actually recommended to me to just eat more iron rich foods, such as beef then add another pill that could be harmful to my sensitive gut. What are your hemoglobins? I carried twins until 29 weeks and 2 days and my hemoglobin was right around 10.1 when I delivered, it fell during delivery, but I had an emergency c/s and by the next week, they were rising again.
Also, as for the constipation. Here's what's safe. I ended up with the ER 3 times with compactions. I have SUPER high progesterone levels and high progesterone can lead to the constipation. Get used to pregnancy constipation, it's SO common!!! But, they were worried with me. We didn't want anymore fissures or hemmorhoids, though I did have my fissures pop open from time to time. That said, Miralax, up to twice daily is SAFE. Just get it over the counter. It's CHEAPER to have your GI call you in a prescription of Glycolax, the generic, so long as you have good generic coverage. I was advised AGAINST taking stool softeners because apparently, long-temr on someone with IBD is not good for their gut. I don't remember why, but that's why we did Miralax. I would mix it with sprite or another carbonated soda or gatorade. It's just a small capful dose. I found mixing it the night before made it easier to drink the next day.
Eat fruits with lots of water in them... watermelon, grapes seem to be helpful for me, etc.
Also, it's always a good rule of thumb to drink 1/2 your body weight in ounces of water. So, if you weigh 150, drink at least 75oz of water per day. I was carrying twins, so I was drinking OVER 100oz of water a day. If you drink ANYTHING with caffeine in it, that negates how much water you drink, so if you drink 12oz of caffeine anything, then you need to drink 112oz of water if your goal is 100oz. That water intake will help the constipation too! I will say that a little caffeine each day helped act as a stimulate to my bowels, so it's definitely not something to get rid of entirely. Everything in moderation.
Sorry if that's more info then you needed/wanted. GL with your pregnancy! I felt SOOOO wonderful during pregnancy..despite all the complications we had with our daughter. I ate all the greasy food I wanted and never flared until after pregnancy. I can't reiterate enough...pregnancy was GOOD to me!
