husband vent

my husband and I've been married 9 years with 3 boys and pregnant with our 4th baby. when we found out he was waaay more excited than me. actually I've been the complete opposite of excited. I did not want to 4 kids. I even tried to get my tubes tied after my 3rd. But I'm trying to be excited and posted on social media I'm pregnant (at 13 weeks) and tagged him in it, but he refuses to put anything on fb indicating we are pregnant. I'm feeling hurt and rejected. am I overreacting? pregnancy hormones has been kicking my butt lately.
