Can I not get a period but still ovulate? PCOS

Had my first miscarriage in august 2016, so I do know what it's like to feel pregnant. I also have PCOS but I still get regular periods every month to month and a half. In exactly 2 weeks my period will be 3 months late. This has never happened. My breasts always get sore 2-3 before my period however they now have been sore well over a week. I took a 25ML test today and it was negative, however I just feel pregnant. Any insight would help?
