Mommy of two wanting #3

I have two baby girls and I want to have another baby it’s been on my mind for a while. Each time I bring it up to my husband it’s a maybe in a few years. I had my kids back to back they are Irish twins 12/02/19 and 12/23/20. I don’t know if I want to get pregnant again because I miss being pregnant or because I’m more afraid that I won’t be able to have more kids later on. I was told by my doctor I had PCOS “polycystic ovaries” when I was 17 I’m now 24 they told me I had two wonderful rainbows babies and doesn’t know if I’ll be able to carry again. I had one miscarriage. 😩 don’t know what to do
