Short Period...confused!

Coryanne • Pregnant with baby #3!
My husband and I are TTC and Thursday I started my first period off birth control. I expected this period to be horrible because I've always heard it is after going off BC. I didn't have any of my usual symptoms leading up to it, and no cramping once it started. It is now 2 days later and it is over. That seems really short to me. Is this normal after getting off birth control? Leading up to AF I took a pregnancy test and it came back negative. Has anyone had this happen and still ended up pregnant?
