I’ve known women at 30 get pregnant. It’s actually very easy to do if one has not had multiple abortions.
I was over 30 when I had 4 of my kids .

Sure. Fertility has not massively declined at 30. It does take a significant dip at about 32 and then another at 36. Yes it is possible of course to have a baby later....my mom was 41 when I was born....but the odds go way down. A woman who has waited until past her mid 30s to even begin trying to have kids has an excellent chance of ending up childless.
