Am i pregnant?

So ive been living with my boyfriend for 4-5 months now. I started my last cycle 11/21 for the first time since i started my birth control (depo pervera took my periods away,and id stopped getting beacuse of the symptom)

My fertile window was 12/1-12/6

12/3 i started getting cramps at night, and sharp little pains in my abdomen.

12/4 i got nauseous and had a huge migraine

And now its 12/6, my stomach is bloated, and i still have those sharp pains

Long story short. To be honest, i just dont want to feel crazy, any advice?
