I loved depo injection, easy to remember and only takes a few minutes. I had very light cycles only about every 4 months.
I really liked depo proevra, it was effective, I only had to get it every 3 months and I only got my period about every 2 or 3 months :)
I loved loved loved nuva ring! Worked awesome and I didn't need to remember to take it everyday. I have tried the pill, which I would forget about, depo provera made me bleed for over a year straight and had to be put on different hormone pills and iron supplements.
I prefer the implanon implant. I got it after my first baby and loved it! That was 4 years ago though and I think now it's called nexplanon.
Sterilization. Preferably male sterilization because it's less invasive, has a shorter recovery period, and has a higher rate of success. That will be our method after baby #2 arrives this summer. Noooo more babies.
