Pregnant or period???

 Me and my bf have been ttc for a little while now my  birth control was supposed to be taken out last September so we thought it wore off but no luck. I finally got it out about 2 months ago and after 2 years I got my first period on 6/12 it lasted 4 days. I'm supposed to have received my period this morning but nothing. The past week or so my breast have been super tender, my appetite has increased extremely ( I eat like all day it seems) also I have had some extreme cramps so bad that I feel it in my pelvic bone/ private area. I don't know if I'm just not used to all the period stuff or what's up. Please help
