Brown Spotting instead of Period

Lacey

My husband and I have been TTC for a year now and my menstrual cycle has always been on point. I was expecting my period this week, but instead got small spotting of brown over the last 4 days...

The kicker, all my at home pregnancy tests have been negative. I read about implantation, but isn't it really late for it? I also have a history of ovarian cysts, so maybe PCOS? Low HCg?

What does it all mean Batman?
