Hi ladies, interested to hear experiences with morning sickness for those with an autoimmune thyroid disease? I have hypothyroidism (Hashimotos) and had very mild morning sickness for week 8 and 9 and that was it! I was always told years ago when I was diagnosed that I'm actually lucky in a way because I will feel my best when I'm pregnant and I never understood why. At a recent endo visit at 10 weeks, my free T4 had dropped a bit and TSH was a little elevated so my endo increased my thyroxine dose slightly. She told me it's normal cause baby is using T4 and that she sees this a lot, that people with autoimmune hypothyroidism before pregnancy tend to have very easy pregnancies with little to no morning sickness.
Did anyone have this experience? Or did anyone with hyperthyroidism (Graves) experience very bad morning sickness? She explained that it's because the molecular structure of HCG is very similar to T4 and if you have Graves before pregnancy, your body often reacts very badly to HCG the same way it does to T4. I find this so fascinating!
