I would be happy to help you.

First- are you aware that the implanon only lasts for 3 years?

Thank you for the followup - sorry for the delay.

The implanon can only be considered a reliable form of birth control for about 3 years, so for the last 1.5 years, you have been at risk for pregnancy.

If your cycles were regular, then one can assume that you likely were not ovulating at the time that you had intercourse (cycle day #10). Most women ovulate around cycle day #14. The bleeding that you experienced might simply represent bleeding that sometimes occurs around ovulation related to a brief, abrupt drop in estrogen levels.

Nonetheless, you need to check a reliable pregnancy test now and repeat this in one week. If it remains negative, then you are not pregnant. You need to have the implanon removed and need to be on some other form of birth control in the meantime.

I hope that this helps and good luck!
