Good luck! you have been through so much with your pregnancy!
I haven't seen any recent papers on thal minor and pregnancy. The last things I saw were old and stated a higher chance of transfusion and/or c-section, but not at an alarming rate. I still think that depends on your overall state of anemia when you conceive and most of us heterozygous thal carriers here remember better and worse times in our life.
My OB/GYN told me that based on my state of health, I would have to be monitored by a high-risk pregnancy expert if I want to have children. It is a little intimidating consider how much I hate having to deal with all this, but I know that if one really wants a child, they just do what it takes. On my doctor's part, it was commendable to prepare me because I would have to take two years off work and that is major life planning. I wish more doctors were as realistic instead of "oh you'll be just fine" and then you are surprised and disappointed.
I don't think people would have fewer babies if they were warned. We have a right to know what reality is. This attitude of heterozygous thal being ignored has harmed so many people by suprising them and traumatizing them with thal major babies. I am never advocating what people should do for themselves and their family, but I know that if people knew their chances for a thal major pregnancy, they would prepare better. And yes, there would be some who would abort or maybe postpone their plans, but maybe if you're not 100% you want to be a parent, waiting is better for the child. And adopting a child is also a great gift and societal contribution.
I am always admiring the people who go through pregnancy no matter what their state of health is, so long as they are committed to taking care of themselves so they can take care of their child. It is encouraging to see how strong and committed you are. I know that your pregnancy was very difficult and dangerous in the end, but I wish you that the hardest part is over.
