Hi Domenica,
Iron deficiency can affect fertility, and thal minor does also have some effect on the ability to have a successful pregnancy. Because your Hb has dropped so low, it would be advised to correct that as much as possible before attempting to get pregnant. You would most certainly need regular transfusions during pregnancy if your Hb is as low as it is now. If there is no endometrial bleeding taking place, then you should be able to raise your Hb with iron and other supplements. Do you know if you have always had a low hemoglobin level? Do you have any earlier test results at any point during your life? This would give you some hint as what your norm is, as with thal minor, it is often lower than normal. This could give some target for what to expect from iron therapy.
I am going to give some recommendations that will help with both your anemia and also help you have a better chance at a successful pregnancy. You mentioned folic acid. This is essential for every woman trying to get pregnant and during pregnancy, as it lowers the risks of birth defects. For thal minors, take 1-5 mg daily, and once pregnant, no lower than 2 mg daily. Take vitamin C with the iron. This will improve iron absorption and will also improve the circulatory system, which is extremely important during pregnancy. Both you and your husband should be taking natural vitamin E. It has been known for decades that this improves potency and fertility. It is also highly recommended in all forms of thalassemia because of its strong antioxidant properties. Get your vitamin D level checked. This is the single most common vitamin deficiency and somewhere between 1/2 and 2/3 of all people tested, test deficient for D. The minimum level should be 30 and there is much research that suggests 50 should be the goal. Most body functions are affected by vitamin D deficiency and fertility is affected. There has been a virtual explosion of information about vitamin D in the past 5 years and doctors are becoming quite aware of this and most will order s test if requested. Take a B complex supplement daily. Eat a good diet with fruits and vegetables and avoid processed foods as much as possible. This will help you overcome the anemia more quickly and also provide more antioxidants, which are very helpful for thals.
As you poke around this site, you will see plenty that testifies that thal minor is not a benign condition, and that for many people it does affect the quality of their lives. However, few, if any doctors will acknowledge thal minor as a cause of any problem. What this means is that you will get little help from doctors in trying to improve your health, so you have to become proactive and learn what you need to do to improve things on your own. Nutrition is a key.
