Could this be implantation?

Sorry for the pic... AF isn't due until 2/16, thinking I ovulated around the 2nd, though this is my first cycle off of BCP in about a year and a half so I don't really know what to expect from my cycle. I didn't have implantation bleeding with my daughter, so I am not sure what to expect. I definitely feel pregnant- mild cramps, boobs feel like when I was weaning from breastfeeding, and I just feel like it- but who really knows! Thanks for any input!!!
