TTC & not sure whats going on?

So i was on depo for about 6 months, the hubby and I decided we're ready for another child so I quit and didnt take my last shot, that was about two months ago. I know it takes about a year for your body to get a period or be ready to conceive but its been two months, no period and no BFP but these pass couple days my breast have been sore like crazy. Very sensitive. Hubby even says he thinks they are getting bigger. Any ideas whats going on?
