Talk to Gynecologist on Gynaecology

I had my femplant (implant) after my first baby one year ago. After that i had irregular periods(one week apart). Doctor prescribed me familia for two weeks but i ate it only for a week as i was breastfeeding and it was effecting my milk production. After that i didnt have any periods for almost one year. Now this month (feb) i had my periods and again they are irregular (one week apart). And from last eight days i am on my flow is medium. Still on femplant and breastfeeding. Kindly tell what should i do? Take familia again... Kindly help... Thanks.
