? Depo: I'm thinking maybe you mean you were previously using Depo-Provera injections for contraception. Most women successfully get pregnant after Depo is discontinued, but it may take 3-4 months, or up to a year to do so. Also, your cycle is disrupted and delay in menses is not uncommon. Wait a week to 10 days after date period expected, and if no period, do another pregnancy test. Good wishes:)
