What is happening?

Okay so AF is supposed to be here in 3 days! Me and my husband did the deed every day of my ovulation time! I’ve been having little cramps nothing like period cramps and my stomach has just been a little weird not sick or anything like that though. My breasts have been hurting so bad the past week and a half and I’ve been having heartburn. My breast never hurt when AF is here and I’ve never had heartburn in my life my husband had to tell me what it was!! I took a test this morning but it was a negative I think. (I feel as though I may have line eyes so I don’t really trust myself!) Does this sound like pregnancy or AF will be here in 3 days??
