2 days late.. Am I pregnant?

 I got off the pill when we got back from our honeymoon in October, immediately got my period. Now I am two days late, I have been testing just about every day and got the BFN!! I feel so discouraged because I really really want to be pregnant. My nipples are very sore, my CM is very moist, thick, like school glue, and I am having minor small cramps. Is it too early to have a positive test?   Am I getting my period and just having irregularity or am I pregnant? Last night I was very very naseous, flushed? Help!
