Feeling like Af will arrive then BFP?

Morgan

Has anyons ever felt like aunt flow would show up any minute then ended up pregnant? I'm 10 DPO and 4 days away from AF. All yesterday I felt like af would arrive any moment (cramps and just that af feeling) but didnt, I woke up morning tossing and turning because again I felt like she would show. (Messed up stomach, cramps) and still nothing. I have taken a test yesterday and it was negative...
