Could I be pregnant?

My husband and I are ttc. I have PCOS so it's been an issue for some time. However I took my second round of Clomid CD 3-7 starting November 3rd. I've had some cramping, minor low back pain off and on, constipation (sorry tmi), nausea off and on, and bad dreams. One of the only, and major, symptoms I haven't had are sore breasts, could I still be pregnant? AF is due in a week so it's too early to test. I'm getting discouraged ?
