IVF help

I need some help..I had a tubal ligation but am regretting it TERRIBLY. I had it 6 weeks after I had my last baby. She will be 1 in 2 1/2 weeks. My husband and I have talked about wanting another baby and have said we would actively try to have one but we have been told that having a reversal is a waste of time and to jump straight into <a href="https://glowing.com/glow-fertility-program">IVF</a>. I know NOTHING about <a href="https://glowing.com/glow-fertility-program">IVF</a> (I have looked a ton of stuff up but I’m still super confused) one of the main things I’m worried about is cost.. I did see it’s super expensive so how could I get help paying for it? Please no hate!!! I’m generally curious because I’d truly love to have another baby.
