Doxy should be ok: The current thinking is that except for rifampin, other commonly-used antibiotics (such as doxycycline and many others) do not alter the effectiveness of birth control pills. This is likely presuming a person is not sick with vomiting or rapid diarrhea, or some other condition that decreases the absorption of a swallowed pill.

Should be fine: Doxycycline has only limited interactions with birth control, so it should be safe for use with your Depo-Provera provera (medroxyprogesterone).
