Am I pregnant?

Franchesca
Hi me and my fiancé have been trying for more then 1 year.. I thought I was pregnant last year in December and it was a false alarm! I was on depo birth control for over 2 years and been off of it for about 6 months now! We have been having unprotected sex and been trying to make a baby! I feel natious if I don't eat' and I feel bloated all the time my boobs are swollen, and if I over think it too much I end up not pregnant. I been cramping a lot, my period is very adnormal but thru the calendar on the app it says I was suppose to have my period 2 days ago. I been cramping a lot! Last month I was late but ended up getting it on the last day of the month! I have mayor backpain and when I sneeze i get abdominal pain, what is more wierd is that sometimes my stomach gets rock hard' and it's not cause I have to use the bathroom! We've tried every position and I still don't get pregnant? Do you think I may be pregnant now? Since I been having a lot of pms symptoms? But no period yet
