For a 30-yo? No; I'm afraid I just understand the fertility curve looks something like an inverted U centered around the late teens. If I had to guess, I think the infertility rate is something like a quarter or fifth by the 40s so maybe half that or less for 30?

This is something you should really research yourself. On the plus side, if you keep notes and you write up your final cost-benefit calculation and actual decision, it'd make a good Article or Discussion post.
