Any advice

Lauren • Married. Me - 21 Him - 24 TTC #1 since 12/14
So I don't understand at all. Hubby and I have been ttc for 14 months now. This cycle has been so weird. It started a week early and now on CD 20 I'm having bleeding? I don't understand? I never bleed in between periods and even though this cycle started early it was still within normal range? Does anyone have any advice. I don't think I'm pregnant according to glow I should have ovulated a few days ago. I just don't understand this it's so weird to me and has thrown me off.
