upset.. any opinions?

I've been trying to get pregnant for 7 years. Couple years ago I found out I had hypothyroidism, heard it's even harder to get pregnant. All I want is just one baby. I've been told my DR. that my ovaries are good and everything I seen a OB once and asked why I haven't got pregnant yet but she never did anything any tests or looked at anything and said I could get pregnant. My thyroid has been finally under control for 6 months. I was also on the depo shot.. I just want some answers/opinions.. it kills me not be able to get pregnant..
