I've traded a lot of time and anxiety to enter a parallel universe. In between the stores and shops you visit are things you skipped over without notice, like clothing shops for kids, toy stores, etc.
There are a lot of skills you learn, and kids in general get far less annoying, because you've now got empathy for their parents, and just smile instead, to give support.
Parenting is a big choice, there are no official manuals, but there is an enormous support group all around you.
No, I don't regret it.
Advice: I feel the strong need to point out that miscarriages happen, 80% of them in the first trimester. You might want to wait until the 2nd trimester before telling anyone outside your very immediate family.
Advice: Your primary responsibility is to parent, you can be friendly right up until that line.
