Period or Pregnancy?!?

My fiancé and me have been trying for a baby for 4 months and we thought this was our month. I have had every pregnancy symptom except puking and tender boobs. AF was due today (1/12). I woke up with nothing and instantly got excited. I kept going to the bathroom all morning, I’d say around 10am I wiped and it was the palest palest pink. One small watery/pinkish discharge wipe (sorry tmi). So I instantly cried, called my fiancé and said we have to start again. It’s now 3pm, not a thing in my pad, nothing when I wipe. Is there a chance it’s not my period?
