So I have been on Levothyroxine 50mg for 2 years and have a 1 year old. I’m trying for another child and have noticed my cycles are messed up. I got tests done and my thyroid is very underactive again - TSH is 6.86. I have now been given a higher dose of levothyroxine 75mg. Which will take 6-8 weeks to work. I got my progesterone tested 7 days after I ovulated, (surge never went higher than 0.4) and my progesterone result is 1.9. Has anyone been in this position before? Feeling really deflated and negative that I won’t be able to have another child. Any advice would be great and please be kind I’m not feeling great today!
