Spermicide?

So I went off the pill a while back, I’m planning on having sex this weekend, only condoms, should I get some sort of spermicide? Have any of you used one before

Which one should I get if so?

Update: so I’m reading that most condoms already have spermicide in them? Is it safe to just use condoms? I really don’t want to get pregnant!

This is my first time having sex off of the pill so I’m really nervous about that
