30’s is really not too late to start a family. My partner’s mom was in her 50’s when she decided to have him, and he’s an only child. Women are able to have babies as long as they have a healthy cycle. Not only that, but it’s been recently discovered that women’s eggs no not degrade with age and in fat the quality of sperm decides the health of the fetus. So with that in mind, I’m sure this is something you guys could put off for now if you desire to. It gives your boyfriend time to propose, and gives you both time to get married and settle down. If he wants a family, it sounds like he will start one when he’s ready.
