4 day period, I think

I had what seemed like a period, I think. At first it looked like pinkish EWCM but still I put a tampon in. The color never changed it was always pinkish. So the 2nd day it was a little more than spotting so I considered it a light period. The 3rd and 4th day was the same as the 1st day pinkish EWCM. This morning I woke up thinking my period was playing with me (((it usually happenes like that, I spot light and think it's over so ilI take the tampon out and next thing I know I have blood everywhere!!!))) well nope it was all just watery CM I think... Should I wait to test a few days? Or should expect AF??? Anyone experienced this?? What was your outcome of it?
