Advice please

So I just had a baby almost 2 months ago and obviously I do not want another baby right now. I'm also dealing with a lot of realization after having my first baby like I wasn't ready and I don't think I'll ever want another one but I don't want tie my tubes in case I change my mind. Anywho what are some ways to keep from getting pregnant? I know condoms & birth control but my vagina hasn't been the same since the third trimester of my pregnancy and it's painful to use condoms it hurts to even have sex but it's doable. We don't have a ton of sex anymore because of it but when we do I just worry about getting pregnant again. I don't see my doctor for another week about my vagiba and birth control so I was wondering if anyone had advice till then like spermicide? Is that a real thing?
