Cramps during tww?

Jen • Mommy to a 7 year old boy and 4 month old twin boys!
I think I got a very faint positive hpt this morning but AF is due Friday and I've been having mild cramps today and sore boobs. I'm getting worried that maybe AF is on the way? Has anyone had cramps very early on? I'm 10 DPO but have a short luteal phase and usually have cramps the day before AF.
