Been praying!

I've been bleeding for almost a week, 6wk 5day pregnant today. Saw doc day after it started last Tues, the sac had grown from last visit and to come back in a week. Bleeding has gotten worse since but nurse says if you're not filling up an over night pad in an hour then to relax and take it easy. Next appointment is Tues in 3 days. I've also been googling (I know I know) but I found out that in old mamas to be aka me I'm 39 with a 15yr old, that we can get cervical polyps that can bleed a lot. Up to weeks which sucks but hopefully the doc will check my cervix along with the Sono! Praying for a heart beat! Praying for bleeding to stop! Has or is anyone going through this too?
