Hi Cayl Hope you are doing good. Femiplan injections contains medroxyprogesterone acetate. After using femiplan for contraception, it may take upto 1 year for return of fertility in some cases. Sonfor your question, yes you need to wait patiently till you conceive. If conception does not occur after 1 year, then investigations can be done to look into causes including your partner. Hope the above information solves your query. Thank you.
