Has this happened to anyone?

So AF is supposed to start today and so far very mild cramps and light light spotting. Normally I have painful cramping and a heavy flow but this is so different. It’s barely there. Could I be pregnant? I can’t take a test until Monday evening since we are out of town with family but has that happened to anyone and they ended up being pregnant?
