Am I acting 'normal'?

So I'm 19 years old and on the 10th September I had a medical abortion due to my personal issues and reasons. In about a month I would be considered 'due' for my baby to arrive and I've noticed these last few months I've been acting differently.

backstory - my older friends at work / colleagues have 2 small children and they come to work with them and we interact with them and have for about 3 years now.

But I've noticed my actions have changed. I'm much more interactive with them, playing with them and feeling in a way this urge to play and be with them and I've seen / felt this change in the last 2 months. I know the kids have grown up and become more interactive anyway but I feel almost drawn to wanting to play with them and want to be with them more.

I'm aware this could be considered 'normal' but wanted to know if anyone else has this feeling or might understand what's going on. xo
