BC question

Mariah • 22.05.13 💘 baby due March 5th 👶🏾🙏🏽
Bit confused so help would be appreciated; post not too do with mee, but I'm talking too my friend and she is on the implant and she gets periods and is on the pill as well too regulate them; my questions are:
• can you be on the implant and get periods 
• can you be on two forms of BC like these two at the same time
