Im I over reacting

Im currently 22 weeks pregnant but for some time now ive been feeling like an old maid... all I do is stay home watch tv or netflix. But today I wanted to go out with my husband to a carribean festival. I had plans to meet with an old friend but afterwards go out to the festival. I informed my husband about it and begged him to go all day but he wasnt for it. But while I was hanging put with my friend he calls me and tells me hes going to the festival with his cousin and going to meet up with his sister.. He does ask me if i want to go but by that time i put it out of my head and was hanging with my friend, and kinda wasnt in the mood then... now just a few mins ago he tells me that the festival is over but now is going to head out with his sister and friend out to a club/party. Again he asks me if i want to go but honestly by this time im home dressed down in my PJ's and no really not interested but kinda upset with him because when I really wanted to go and was really excited he wasnt into it. I didnt mention that im upset cause i dont want to ruin his night but i am. Am i over reacting.?
