My SO was speaking with his ex and their conversation seemed harmless but now I'm kinda sad and worried

Okay, first of all, you have moved WAY TOO FAST. Seriously, WTF? Eleven months you have known this man. You are twenty one and tying yourself to him for life. Not even seven months in, and you are pregnant. I really hope you've thought this through (but based on your insecurities I don't think you have.) Love waits, girl. You don't have to rush when you've met the right person, you really don't. I really hope this works out, but you've really made some terribly rash decisions and moves. Where are your parents? Do you have a support system for when the baby comes? Are you going to be a SAHM, or go back to work? Have quality childcare lined up?

Okay, I'm sorry, but I felt that needed to be said.

That's conversation sounds harmless, and actually sounds like a good sign. They wished each other well and had a harmless catch up via messenger, and that's done. That's it. If this really bothers you, you should tell him how you feel and maybe ask that he limit contact and possibly limit what she can see on his FB.
