if you are breastfeeding the only pill you can take is the mini pill and you have to take it at the same time every day otherwise it won't work, I tried that and I couldn't remember to take at same time every day even with using a timer. I ended up getting the mirena IUD and that is good up to 5 years and is safe to have while breastfeeding.

I gained a lot of weight on the pill, and I was on a bunch of different brands. it all depends on the individual though

hmm I might just have to try that. I just had my second child 15 days ago and ain't wanting another anytime soon.
