Am I pregnant or have an ill issue ?

I’m never really late when it comes to getting my period the latest I been has been by 2 days so anyway I was supposed to get my period on the 13th I haven’t ??? I’m kinda worried but not too worried I’m 25 and I’ve heard your cycle can change as you age so I’m still hoping my period will come soon because I been feeling cramps since last week ,yesterday was really bad but I kept myself together I really don’t think I’m pregnant I haven’t had any implantation discharge only lil bits but I’m saying like small bits so basically not enough to say it was implantation I have a pregnancy test but I don’t want to test yet I think I’ll wait for my period, have any of you experienced this ??? I’m also thinking of making a dr appointment so he can tell me if I have any issues going on because I really don’t think I’m pregnant I don’t feel it . Any advice would be appreciated. Is this normal ?
