Birth control help

I'm 10 months postpartum. My husband finally decided that I should go back on BC because he doesn't know when he'll have the time to get his vasectomy done because of his hectic work schedule. I haven't been on BC since 2013 and I'm loving not being on hormones.

Anywho, I messaged my OB for help and she just sent me a link to the different options of BC and it's information. She also told me I can't use the pill, patch or ring because it'll effect my milk supply (still nursing). We don't plan on having anymore kids and my husband will eventually get his surgery (he volunteered).

Any suggestions? Help please.
