Uterine Bleed and Bedrest

I had an ultrasound at 7w5d and baby measured a little smaller than the doc originally thought but s/he had a strong little heart beat at 147 BPM, yay! 

The ultrasound also showed a small tear or "bleed" in between baby's yolk sac and my lining. Basically the beginning of miscarriage due to me having Progesterone deficiency. I was put on immediate bed rest and extra progesterone and told not to even sneeze so the tear remains small while the sac grows. 

Has anyone had a baby with this "bleed" before? I'm scared it will affect placental growth and cause a bunch of problems.
