If you have regular periods (& you can confirm ovulation in one of the cycles), you need not worry about ultrasound
findings. Normally when a woman is having regular menstrual cycle of around 28-30 days she makes on follicle (which contains one egg) in one of the ovaries. The follicle ruptures to release egg around midcycle(14th day). If you had intercourse around that time, sperm will reach the egg, fertilize it & embryo (baby)is formed. In women with irregular cycles, they are not forming follicles to release egg monthly & need medicines to do that.
Regarding your infertility
problem, its better to go (you & your husband both) to specialist, get investigations done & get proper treatment.
Wish you good health.
