Hypothyroidism

After my first miscarriage my doctor did blood work and I was diagnosed with hypothyroidism. I was devastated. Now I'm on medication for it. It's been difficult adjusting to the medication. I've never had any health problems and now this. I'm wondering if this is going to affect my menstrual flow. If it's going to affect me from trying to concieve a baby. Or if I due get pregnant, will the medication affect the baby.  So many questions are running in my mind. Do any of you ladies have hypothyroidism and how has your journey been? Is your menstraul flow normal and were you able to conceive?  Or have a healthy baby?
