That's interesting. Are you having sex around your ovulation period? Maybe try OPKs or a tracker to make sure you're having sex around the right time. Also, ask your doctor if there is anything you can do to increase your odds. There is instances where a person has unexplained infertility. Hopefully that isn't the case and you'll be pregnant soon. Good luck!
