Implanon - need advice ASAP!

Maria

So I'm deciding to put the implanon back in but my period has passed and I've had unprotected sex with my partner but took the morning after pill straight after. My question is, should I wait til I get my period just to be safe to know I'm not pregnant and then get back on the implanon or should I do it now as I've taken the morning after pill so everything should be fine right...?
