Car sick a sign of pregnancy?!?!

I get car sick sometimes but that's only if I'm on a long ride and if I look down for a long period of time but I haven't been that way since I was younger and for the past 3 days I've been super car sick. Is that a sign ? Also 2 days late of period and tender Breast with no sign of period symptoms and normally I'm bitchy and cramping bad but no sign.
