Pregnant or Not?

My periods are always regular like spot on I can always predict the day. This month however I was two days late. I started discharge this morning but it was a color that I had never had before. Any other time it’s a red bright red discharge. However this time it was brown/pink. Also I always get cramps a couple of days before my period and those cramps are severe. This morning I didn’t start cramping until after I saw the discharge. So is this a period and I’m just paranoid or am I really pregnant?
