Questions About Hypothyroidism

Hello! I was diagnosed with Graves’ disease at age 15, unfortunately had to get it destroyed via radioactive iodine at age 19. Since then, I’ve really struggled with trying to keep up with my health as I have a number of other physical and mental illnesses that affect me. I was not trying to get pregnant, but to my surprise it happened around early October. I didn’t find out until early/mid December. I had an appointment/checkup with my endocrinologist a few weeks before I conceived (late September) and I was very under active. He told me normal range for me should have been between 0.2-4.5 I believe, something like that. Mine read a 6.3 (over 6 for sure). Some crazy stuff happened and my thyroid hormones were taken and I won’t get into it but I went a week or two without taking any at all. I was on 137 dose btw! As soon as I could, I started taking my hormones again. When I found out I was pregnant I was honestly so shocked. I know thyroid hormones are important to the development of healthy babies. I’ve since talked to my endocrinologist and family doctor and I’m on a dose of 150. I’ve had an ultrasound and a few blood tests, but I know any little inconsistencies can really mess with the accuracy of the readings and it takes a few months of consistent consumption to get an accurate reading. I don’t believe I’ve missed any doses and I’ve been good with my medications since but I’m so worried about any lasting damage that could have been done. I’m so sorry if that was long.. My question is does anyone have experience or know anyone who’s been through this kind of thing? I know there are some things that can’t be detected during pregnancy but I have been told my baby is developing okay. My endocrinologist is not the most competent and that really scares me but thankfully my family doctor has my back and puts in a second opinion.I do plan to switch special and I’m waiting for a callback but it’s looking like I’ll have to deal with mine for the rest of my pregnancy. What are dangers exactly? Will my baby be healthy or have I messed up badly? I’ve heard that if you’re quick to correct your hormones you should be fine, but 2 weeks is a long time. I feel so sad thinking about it and any insight or support would be appreciated. Remember, my thyroid is completely gone. It’s so difficult finding any information on the topic and I just feel lost some days.
