Help anyone else have this?

Kayla
Alright ladies af was 3 days late and I've only been spotting for about a day and then it stopped I'm afraid to take a test because I don't want a BFN has anyone else ever had this?? I'm 23 and never had anything like this!! I've also had cramping but i have endometriosis so it's all weird because I always cramp!! Any help would be great 
Thanks so much
