If you're BF your choices are pretty limited. You can only take the mini pill (progesterone only) as the combined one can mess with your supply. I was on Microlut and wasn't really a fan. I didn't get AF at all (which is good in a way but I am paranoid and don't want another surprise!) and I put on a few kilos.
DS is going to wean soon by the looks of it so I'm getting back onto the combined pill (what Raupe was describing) I was taking before I fell pg...Brevinor I think it was called. Suited me perfectly, no weight gains, bad skin or mood swings! And it eased my period pain and isn't expensive (about $25 per quarter).

The pill is a bit hit and miss, what works for some doesn't work for others. So I guess just start with one and see how it goes.
