Hello dear,
Nexplanon is a reversible long term contaception.
It contain etanogestrel.
Its failure rate is only 0.05% after perfect use.
I think there is no chance of pregnancy.
But if you want to check just confirm it by Urinary pregnancy kit, 7-10 days after regular date of period.
Also note the common side effect of nexplanon:
1. Irregular bleeding and spotting
2.Mood swings, Weight gain, Headache, Acne, Depressed mood
3.
Vaginitis may be cause in your case.
For vaginitis you shold take following treatment:
You should use following single dose treatment:
1. AZEE 1000 mg (
AZITHROMYCIN)
2. TINI 1 G (
TINIDAZOLE)
3. ZOCON 150 mg (
FLUCONAZOLE)
or you can take tablet
metronidazole 400 mg three times a day for three day
So very rare chance to become pregnant in your case.
Exclude other cause as I described above.
Best regards.
Dr. Sagar
