Please some opinions

Hi im trying for a baby for 12 months now and nothing happened so me and my husband checkt ourselves I've done blood test for hormone levels and they were ok and my husband had semen check and the levels of sperm were ok. The doctor says is just the timing that the baby is not coming yet. But from 11 years old i have a lot of discharges and i hade that check a lot of time and everybody told me is natural discharg nothing to worry. Im woring maby i have fallopian tubes blockt and thats why i cant conceive. Can a ultra sound show if your fallopian tubes are blockt?
