I got what I thought was my period on dec 16th (2 days early). It only lasted 3 days and was so light in comparison to my regular periods but I didn't think anything of it. I'd been feeling a little off for a while, and on jan 2 I started bleeding heavily and it is just now stopping. Could the first have been implantation bleeding and I've miscarried? I've never had irregular periods, so this is totally strange. We've been TTC for only a few months.
