Going to make an appointment

Once the new year has arrived, I'm going to make an appointment with a gyn. What I thought would be flow, turned out to just be a one time event that one day and nothing since. This isn't normal, even for me with my PCOS. A part of me wants to take a pregnancy test, but a part of me realizes that I need to just accept that it is probably just a hormonal problem. Which ever it is.....Praise be to God!
