if you have been sexually involved and not using a different contraceptive then yes definitely get a pregnancy test. while it can happen not having a period for five months after the implanon was removed deserves a consultation with your women's health specialist to find out a reason for your delayed menses.
i had my implanon removed 5 months ago and i still havent had a period. i want to get pregnant. should i be worried? . how long should i wait to see a doctor? is this normal?
