Any ladies with fertility issues?

I am only 24, me and my SO have been trying for 2 year (he’s 27).... SO has normal sperm, i have had my bloods taken and they have come back normal. Docs are sending me to hosp for ultra sound etc but I am on 3 month worth of iron tablets first and once I have finished taking those I will be referred (formality)..... I am just wondering if anyone has had any normal bloods back but had something wrong with ultrasound? We have sex on all the right days etc so I don’t know why it’s taking so long!

I have regular periods and I ovulate?
