Group Strep B

Shari
Hi ladies, 
I have been bleeding on and off for a week now and have my second early scan tomorrow to see what is going on. I just heard back from the midwife that I have group b strep, has anyone else had this and it has caused bleeding? I know all about what the risks are with labour when you have strep B but not a darn thing about early pregnancy. Anyone?
Thanks!
