What would you suggest?

I'm almost 4 months post baby and can't decide a good birth control to go on..
Before bub I had the implanon in for 2 years but had it taken out cause I started bleeding non-stop. The day I had that out I started on the pill, but I was bleeding still at random times while not just taking the sugar pill. I then surprisingly fell pregnant and had the doctor tell me it was probably more aless that my body had rejected it.
What would others suggest to use? I quite liked the implanon but I don't want to have the same bleeding problems again..
