Could I be pregnant?

Hello all!

I just got off birth control on December 18th. Never really had a "real" period on birth control. So since I wasn't sure when I was going to ovulate I kinda took guesses and did the BD pretty often. Still no AF. My boobs feel more sore than usual for AF and I also have very sensitive nipples which is new for me. Otherwise some light cramping but nothing major. Just not sure what my body is doing. I am going to test at the end of the week but I just feel like my body is confused! Anyone else have this?
