My girl friend is on her 150 mcg levothyroxine and is on her first depo-provera provera (medroxyprogesterone) shot. we always have unprotected sex, can she possibly get pregnant?

PREGNANCY: Depo Provera (medroxyprogesterone) shot protects you x3 months. If her mens is delayed, do a pregnancy test to find out.

Usually not: The Depo Provera (medroxyprogesterone) is a fairly effective contraceptive when taken on a regular schedule. The levothyroxine has no effect either way if she is on the proper dose and thyroid tests are normal. There is no 100% effective contraceptive except surgical procedures or abstinence.
