I believe I had chorioamnionitis after my cerclage & my ob stated I only had bv. A month later was hospitalized & lost baby. I'm 6 weeks pregnant & worried?

Relax, but see an OB. Chorioamnionitis is very rare in early pregnancy and fairly rare after a cerclage (though it does happen). Bv can be a risk factor for certain pregnant women, and in your case you should be tested and treated if it is present. You will want to see a high-risk pregnancy specialist. They can help decide if you need a cerclage again, when to place it, and what type to place (there are three kinds).
