Which kind of BC after baby

Alli • Grace 10-8-18 ❤️❤️

So I’m 8 days pp and made my 6 week appointment yesterday and they asked if I was planning on an IUD or nexplanon and I said no. But it got me thinking, what type should I use? Before, the BC I was on made my periods all outta wack, sometimes I’d get it every month, other times I went a few months without, there wasn’t any pattern. I think it actually caused me to be misdiagnosed with PCOS because I got pregnant after only 3 months off it. I was using the pill, I don’t remember the specific kind. I also want to make sure it doesn’t dry up my milk as I’m aware some can. Any suggestions?
