so confused...

6th round of clomid was last month, ovulated on schedule, took a pt on 4/7 got a vfp figured it could be to soon and decided to switch brands test again last night since AF didn't show yesterday bfn. AF is now 2 days late, sore breast, back ache, sick feeling, extreme fatigue, and been having mild cramping for a week. is it the clomid or still a chance I could be pregnant?
