No AF symptoms and almost that time

Christina • Have a 7yr old girl and after an ectopic 4years ago finally got pregnant again and had my second girl this September!
I usually get AF symptoms a week/week and a half in advance and I'm suppose to be getting it in 3 days. It's weird because I always have the worst cramps and hunch over because it's that bad! I was wondering if anyone has experienced this and been pregnant with no AF signs.
