anyone in the same boat??

27 years old. Been trying for over a year now. Got pregnant  2/2016 but ended in miscarriage. I know exactly when I ovulate, I know my fertile window. My cycles are always on time. (26days) my husbands sperm is fine cuz we've ran tests. I don't know what else to do. Tried preseed but husband doesn't like the feel of it. Anyone else in the same boat? Anyone know exact cycles? Kills me every month. I don't know if I should start looking into fertility visits with the doc. Thanks in advance
