I know this is the last thing a young person like you wants to hear (especially from an old chook like me! - 39!!) but you really do have time on your side. I dont know you or your circumstances, but there is a much better than average chance that you will meet someone and have a child with them.
Dont rush it. In other words, dont rush into a relationship that may be less than perfect for the sake of having a baby. Because, like the old RSPCA ad says "A baby isnt just for Christmas, it's for life". They may actually have been talking about puppies but you get my drift...
Your signature features you juggling balls. Well, have another baby and those balls will double - at least. That's why it's so much easier if you are in a stable, loving partnership. That way you can both juggle the balls together.

I hope you find what you are looking for
