Brown discharge turned to period like bleeding

Sarah
Woke from nap this evening and had period like cramps for 2 hours followed by dark red period like bleeding. 6 weeks 2 days along, calling Ob when they open at 8, had very light brown discharge with wiping in the am, not going to ed since I can get a hold of my Ob in the am, still bleeding buts it's just like a period type blood, really sad scared and nervous, tons of support and positive thoughts from my hubby and mom, please keep your fingers crossed for me!
