lazy!

Am I over reacting by being very annoyed at my S/O. We have a wall calendar in our bedroom, which i put everything in. Including all my midwife appointments. This 28 week appointment to day has been on there for weeks. I've reminded him recently. 
I tell him last night when he gets in from work and he's now um-ing and ar-ing about whether he's gonna come. (He's told me "I'm there for you I'll be at everyone, I'm not missing any") 
So I ask again when we're up late last night, still not decided. 
I get up with my alarm have a shower, ask him again. He says, "what time do we have to leave" I tell him, I get ready.
He returns to the room and while I'm getting dressed jumps back into bed. 
I say "so I guess your not coming then"
His reply " I'm not feeling too good." Really?  I just tell him "whatever" and finish getting ready. 
As I leave he's all tucked up in bed and says " let me know how it goes" I do not reply.

I wrong for being annoyed because right now I feel like punching him in the face. (Currently on the train to see the midwife alone) 😡😡😡
