Is it possible to get pregnant on the Nuvaring while you are taking penicillin? It took me twelve days to finish the perscription. And we were intimate multiple times over the time that I was on the penicillin. I had read that there was study in Europe that said these antibiotics do not the Nuvaring.

I've heard for years that taking antibiotics while on The Pill could lessen the effectiveness of it. But, since NUVA Ring administers the drug through the skin I don't know if the same applies. I was able to find this information:
If NuvaRing is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining NuvaRing with the following:
Antibiotics such as ampicillin and tetracycline
Penicillin is an antibiotic so I would assume the warning applies to it as well.
If you find yourself in this situation again I recommend doubling up on birth control with a spermicide or condoms just to be on the safe side.
