Thank you for your query.
Petogen can give rise to abdominal discomfort, nausea, vomiting
, faint feeling, breakthrough bleeding
. You seem to be having most of them. Though inj. Petogen is a long acting contraceptive
but it shall be advisable to use some barrier contraceptive to be on the safer side.
I hope I have answered your query to your satisfaction.
Wishing you all the best.
