Contraception

Okay, so I've been on the implant since November, had a baby in August and still bleeding quite a lot I kinda want to ride it out until 6 months so my body can get used to it but my husband is telling me to go on the pill as well (apparently it can stop the bleeding) or to get the implant taken out and go on the pill. I said I don't wanna mess with my body too much PP and want to just ride it out. I also got a bit annoyed at him as he's getting pissy at me - I'm like sorry but it's my body you should just say whatever you want to do is okay with me and I think he's being a little selfish cos he wants to have sex regularly which I agree is important but it's my body like let me do what I want. When I'm not in my period which isn't often - we do have sex 2 times a week when we can. Am I wrong here?
