Pelvic pressure

Would anyone know...I have been having cramping for a few days and now I have pelvic pressure. According to glow I have just finished ovulating and I was chalking up the cramps to that but now I have pressure and that is not common for me. I had my period in November which was a strange one. Has anyone else had pelvic pain in early stages of pregnancy? I am not sure if I am pregnant or not.
