Could I be pregnant?

Ashly
So my calender says I should have gotten my period making me 3-4 days late. I deleted the predicted period and it says I could get it this Tues.
Yeaterday (TMI) I had two half dollar sizes of snoty clear like substance on my toilet paper when I wiped. Since last night I have had tightness in my uterus and cramp like sensations almost like flutters.  
The cramps may I add are a little intense.
Is it possible I could be pregnant? 
 We are trying to have a baby;so not trying to get my hopes up. 
Any advice? Thanks ladies.💕
