CONFUSED, can I be pregnant?

Anonymous
I'm alittle confused and worried since , I was on the depo shot birth control for 3 months I decided I wasn't going to continue bc I had a lot of headaches. I was suppose to go back on September 26 to get my second shot which I didn't. I haven't got my period at all. I do know that the depo shot takes time to get your period back and that it can take up almost 1 year.

Now the reasons why I'm confused and think I might be pregnant is that my boobs actually grew alittle they are more fatter even my boyfriend mentioned it. I had like 2 weeks straight with upper back pain , I don't know if that counts. Also a lot of headaches but from the back of my head and some what nausea during the day or as soon as I wake up but I haven't vomit. Now does it sounds like I'm pregnant?
