When will be my next period Im confused now....?

You probably will revert to your old 29 day cycle. You won't start on the same day of the month, but about 29 days after th last period, or about the 30 of January. After the mix up though, you cycle may be a few days longer. If you still don't start by the 10th, I would recommend another pregnancy test. It really just sounds like your body is adjusting to a new cycle. We all do at times and it can be a pain until your body regulates itself again.
