What should you know about your period with Nexplanon?

The implant releases etonogestrel, a progestogen that prevents ovulation and changes the lining of the uterus. As a result, bleeding may become lighter, heavier, more frequent, less frequent, or irregular. Spotting between periods can happen, and some people stop bleeding altogether. A new pattern is not automatically a sign that the implant has moved or stopped working.

Track bleeding days, spotting, cramps, and any medicines you take. This record helps a clinician judge whether the pattern is settling or needs treatment. Take the implant exactly as directed by the inserting clinician and do not remove it yourself. If bleeding is troublesome, ask about suitable options after pregnancy and other causes have been considered; a hormonal coil is another contraceptive option to discuss.

Arrange prompt medical advice for bleeding that is very heavy, keeps worsening, or is accompanied by marked weakness, dizziness, severe pain, fever, or a positive pregnancy test. Seek urgent help for fainting, severe one-sided lower abdominal pain, or bleeding with collapse. A clinician can also check for infection, pregnancy, or another gynaecological cause.

Ask which bleeding changes are reasonable for you, whether your medicines could interact with the implant, and what evaluation is needed if the pattern continues. You can also ask how the implant compares with a hormonal coil for bleeding control and contraception.
