Early period?!?!

Jenna
Thanks for stopping by! I have a quick question. My DH and I have been TTC  for 6 months. This month AF was due on the 8th. I had bleeding (normal to light) on the 4th and 5th. Nothing on the 6th and some bleeding on the 7th. I haven't had anything since then. I am normally regular to the day glow calculates and my period is 5 heady days and 2 days of spotting.
​What's going on?!
