Light period then cramps before bfp?

Hello, looking for bfp stories to help me get by! I was on vacation and hiking alot this month when I had my period, and I️t only lasted 2-3 days, dark blood but light for me and then stopped and I’m usually 5-7 days. I thought I️t was due to extra activity but I was only on vacation 2 days before period so didn’t seem like enough time to effect I️t? Now a week later have had light cramps off and on for 3 days. No other symptoms. I’m hoping this is the month but don’t have any test right now and trying to wait! Let me hear your success stories!!
