It is possible that you are pregnant. The only way to really be sure is to see if you miss your period and take an HPT. I am hoping for you that you are pregnant!

But also keep this in mind, there are some women who spot in between periods. Some do, some don't. It could either be this, or implantation bleeding. From here its just a waiting game. Good luck! :)
