did you know you were pregnant before your AF?

Did you ever feel pregnant despite your BFN, then got your BFP? I have 4 days till AF is due, but I swear I am pregnant. There's just this feeling I can't shake. I didn't symptom spot the month of Nov, Dec, or Jan.. & now randomly this month I just feel different. Took a test 7 days before, 6 days, & yesterday at 5 days before, but all negatives. I don't feel sad though cause I know I'm pregnant. Woke up drenched in sweat last night with a dream that I had 2 test test, one had 2 lines, the digital said 1-2 weeks pregnant. I know dreams don't mean anything lol, I have other unusual symptoms as well & I know we did the deed the day I ovulated. Has this ever happened to anyone? My last pregnancy I felt pregnant, but it was my first so I wasn't sure. Having the same feelings now.
