Sperm Donor

Hey everyone, is anyone using a Sperm Donor? I've been TTC via known sperm donor. Been on Prenatal vitamins since Jan 2015, started TTC since Feb 2015. Used Preseed, CM check OPk. Any advice? Oh and I'm turning 36 in 2 weeks so age may be a factor. Has anyone tried Clomid? Or should I go straight to <a href="https://glowing.com/glow-fertility-program">IVF</a>?
