Hep B & Rh negetive shots during pregnancy

[saganaga]

I'm pregnant & due in June. Next month I'm due for the 3rd (& last) round of my Hep B shot & for the Rh negative shot. I was reading in a recent Mothering issue about these & them having thermisal which has mercury & this can be passed on to the baby in womb. I'm concerned about the mercury---can Hep B be delayed or just dropped? Is there an alternative to the Rh negative shot? Can I demand that these shots don't have thermasol?
Thanks for any help/advice/experience,
Rachel

I don't know about HepB, but I do know that J&J stopped using thimerosol in Rhogam several years ago, just ask your provider to verify their stock before you get the shot (they may still have some on hand that has the preservative). I have had 3 Rhogram shots so far, 2 in my 1st pg (one at 28 weeks, and one after my B+ son was born, and one this time at 28 weeks again) All 3 of my shots had experiation dates WAY in the future, and I had the nurse who was administering the shot look at the package with me to be sure each time that there was no mercury preservative.
