Last month had sex every other day during fertile time. Now this month had sex on day 11 nothing since. I ovulate around day like 18 or 19 . Am I going to miss my window as I am on cycle day 15. Husband says yeah we will have sex then always tired makes me upset as we are getting older and feel like it’s never going to happen cause I am the only one putting in the effort. Plus we have been trying for two half years.
