Hypothyroidism and getting pregnant

Sara
Hello everyone. I have been trying to conceive for three months now with no luck. I was diganosed in May with hypothyroidism and they put me on 25 mg of synothyroid. I went to blood work this week and they called me and said my levels are elevated again and to increase my dose to 50. I am so frustrated because it just seems unlikely that I will get pregnant or have the family I've always dreamed of having. Anyone else been diagnosed with this before they had their first child? Most people are diagnosed after they already have a baby.
