Hi Kayla,
Your hemoglobin level is 12.5 which is normal. Your RBC is 5.55 which is slightly higher than normal and expected with thal trait. The below 8 you are asking about would refer to the Hb and not the RBC, and yes that would be a serious anemia. Your numbers are all what would be expected from an alpha thal trait. Your blood work will always show low MCV and MCH and this only refers to the average size and volume found in a test. Because some of your red blood cells ar smaller than normal, these numbers come in low for alpha and beta carriers. As long as your Hb stays above 11 when not pregnant, you are doing fine. During pregnancy the Hb will drop as the blood volume increases, diluting the blood a bit with fluid, so the measured Hb will appear to be lower than it really is when pregnant. As far as your blood tests, no worries there. Natural sources would be natural vitamin E. Synthetic is a by-product of industry and should be avoided. If you see dl-tocopherol, don't take it. Natural will be expressed as d-tocopherol.
Of naturally fertilized eggs, only about 1/4 will implant and become successful pregnancies. Chromosomal abnormalities are one reason for this. This may have absolutely nothing to do with thalassemia. There might be a connection but only by chance. I would not assume that it was a defective sperm or egg, as it could be either or just an irregular development that caused the miscarriage. With IVF, you can expect failures and almost everyone I know who has gone through this has had failures before having a successful pregnancy. You can't expect any better percentages with IVF than the 1/4 in natural pregnancies. Once you commit to IVF you just have to expect and accept if it doesn't take. I would suggest continuing to try naturally also, as we have seen in this group that moms who were told not to expect a high chance of successfully getting pregnant, have gone on to have more than one child. My brother-in-law and his wife were told they would never have children, adopted two girls and then the wife got pregnant with a third child. Don't assume that low motility totally rules out anything.
I am sure your new doctor will agree that you have to be patient with IVF. I understand how disappointing it is when it doesn't work, but I have seen a 40 year old thal major have a child from IVF after two prior failed attempts where there was implantation that detached. Her spirit was an inspiration. She never expressed anything negative but had faith and kept trying and had a very healthy little boy. Stay strong for yourself and your husband. It may very well be that the miscarriage had nothing to do with thal and was simply chance.
