Should I secretly use contraception?

My husband and I have two kids(3 years and 8 months). For the past few weeks my husband keeps saying that he wants us to have another child. I have told him that I would love to, but not yet. We can’t seem to agree on it because he keeps insisting that he wants us to get pregnant, but I keep saying no. This has become an every other day conversation because he keeps bringing it up, and I keep telling him that I am not ready. The last time we had s*x, he did not pull out afterwards… when I spoke about it, he said that he forgot to. Knowing him, I know he did that purposely. We don’t use cond*ms either. Would it be a break of trust if I secretly get implant contraception without him knowing?

I am in junior high because I refuse to spell specific words? Hmm on a contrary I would rather be safe than sorry on this app. I don’t know what the rules are so I would rather not have my account deleted for breaking any rules. Also, be kind and considerate that some adults may also still choose to not use vulgar words.
