You have gotten negative pregnancy
test with spotting 4 days ago.Implanon
is birth control intradermal implant and efficacy rate is more than 99%. Spotting or irregular bleeding may be due to side effect of the implant or hormonal
imbalance caused by stress/ emotional upset etc.
Don't be much worried about this and try to avoid stress. If further irregular spotting appears, then consult with your gynecologist and need some investigations to rule out pathology.
Maintain genital hygiene. Be well.
