Trying to decide when to make it public....

This is my second and last baby I’ll ever have....I didn’t announce of Facebook with my first until I was almost 8 months pregnant...I was embarrassed I guess I wasn’t with her dad and he didn’t want anything to do with her.....6 years later I’m 12 weeks tomorrow and am with the baby’s father and have been for a little bit but we haven’t been together even a year yet and he already has 5 other children.....he was NOT happy about it.....he’s come around now and accepted it but I’m not sure when I should put it on Facebook....I haven’t talked to him about it yet I’m not sure how to approach it....I don’t really talk about the baby or how I’m feeling much because I know he didn’t want this so I try not to make it so obvious and in his face so to say.....I kind of want to make it public now instead of waiting but I don’t know how he’s going to feel about it....
