I have to agree with BUBBA1028. I was basically a worst case scenario for naturally becoming pregnant. On top of having the J-pouch, my colon actually perforated and I was/am filled with scar tissue. I had to have adhesions removed because I was getting pulling and blockages. The Dr who did the adhesion removal surgery was actually an OB and he said it looked bad (someone had also left one of my fallopian tubes stapled to my abdomen....) Anyway, after getting older and realizing I absolutely wanted kids, I began to panic about this. I planned my PhD around qualifying for IVF (insurance almost never covers it btw so be super careful about your career/where you live if this is extremely important to you). I would have been open to adoption but my husband has health issues that basically disqualified us from adoption. On to the good news, after spending time freaking out, bothering my doctors about my odds, and arranging my life around future IVF treatment, I downloaded a good fertility tracker app (Glow) and got pregnant the first month I obsessively tracked my cycle. We haven't tried again so I don't know if I just got insanely lucky. I would definitely keep fertility issues in the back of your head going into your mid 20s early 30s but also remember that who knows whats going to happen when you actually try.
