Hello, The pregnancy hormone takes at least 3-4 weeks after an abortion or a delivery to disappear and as such, it is possible to get positive tests for pregnancy for some time. Sysron is a progestogen and is being used here to induce a period. You can get your hormonal profile if you wish to know the reason for the delayed cycle in spite of a successful abortion. Sometimes, the ovaries need kick-back in the form of external hormonal support to revert back to normal cyclical pattern and the medication helps to achieve that. Hope your query has been answered. Take care.
