Are baby blues temporary?

I just had my first baby 12 days ago. Every day I cry excessively and it takes a while to get myself back under control. I have a lot of support and don’t really feel overwhelmed...Half the time I just look at him and how much i love him or think about how sweet he is and burst into tears. Or thoughts about our hospital stay (he was in the nicu for 6 days) bring back sad memories and set me off into a weeping fit. It’s embarrassing. Will this subside when my hormones regulate (if so how long?) or should I talk to my dr about ppd? I don’t want medication unless necessary but the crying spells need to stop.
