Spermicide ??

Hello!

So me and my boyfriend started having sex recently. We used condoms the first time and every time after to make sure we were safe. I’m personally afraid of birth control because I’ve heard some horror stories like gaining weight, lost of periods and mood changes.

I heard of spermicide recently, has anyone tried spermicide? How effective is it? Any suggestions?

Is spermicide another method of contraception?

Thank You in advance :))
