[|Human|] I have been on the implanon now for 18 months and have been sexually active the whole time and never got my period. I am now back with my sons father and have got my period after 18 months of not having it..:/ we have been sexually active I m a little worried
[|AI|]  Hello, I have gone through the query and understood your concern. Return of ovulation takes 1-2 months in the majority after removal of the implant. Other factors which may influence the ovulation process are weight changes, stress, hormone disturbances arising from cysts in the ovaries as in polycystic ovarian disease, infections and the use of certain medications. Since you have seen the period, which is essentially a with Chat Doctor.  Either case, you should see your doctor for follow up after two months. Hope this helps.
