Arm implant vs pill

Destiny

I have been on the arm implant for almost 2 years. The perks of it is I only get my period every 3 to 5 months....the downside however is I've gained a lot of weight since getting the implant and I just can't seem to lose it. I'm debating on getting the implant out and trying the pill again. I refuse to try the iud or depo shot. So my question is what pill in your opinion works best? Thank you in advance.
