My boyfriend and I have been ttc for about a year now. We are using this app and ovulation tests this month for the first time. I have had two kids and a miscarriage previously but he has none. I've been reading some posts that talk about using certain vitamin supplements and was wondering how those have worked for people. We're starting to get a little concerned it's taking so long. It's not stressful but every af gets a little more depressing.
