Unusual AF ... Opinions? ??

Hello ladies ... so I was suppose to get AF sept.3rd ... I Got her it today I was 4 days late ... I tested BFN the 3rd of Sept ... I never retested ... now I usually get sore boobs with AF but this month my boobs are so sore they feel they are throbbing. .. and my nipples are so itchy !! I don't ever really get itchy nips! it's driving me nuts ... but the AF is very very heavy too bright red cramps horrible and I felt very weak and dizzy earlier this evening. . the morning my af came I had a dream I was in labor but way to early .... ?????? can you say weird .... could I have been pregnant ??? had this ever happen to anyone or something similar to it ....
