Period or Pregnancy?

TaVaria

My period was suppose to come today. It Hasn’t. Instead i’m cramping really bad. Also i noticed a thick white discharge in my underwear. Kinda looks like a lil bit of blood too but no period, not even when i wipe. I tried to conceive! Not sure if it’s just late or what. The hospital told me earlier this week i was not pregnant, not sure if thats because it was too early.
