Overreacting?? Or not (a lil TMI)

So my SO and I have been TTC for the past 5 months and this past week was my fertile week and my peak was on the 9th and we didn't have sex cuz he was tired cuz he was up at 3am that morning(actually he never went to bed) so I understood cuz he had been up for 20 hours. So the night of the 10th I got off work before he did so I got all cleaned up and put on something sexy for him. He got home and showed then came to bed. I rolled over and was trying to play and he just rolled the other way and said he was tired? so then last night I was completely naked when he came to bed. He cuddled next to me for 10 mins then rolled over again!!! So I asked him if he was ok cuz normally I can't get him to leave me alone for a night. He said he was fine just really tired form his 20 hour day. So then today I was on our ipad and went to look something up on Google and it opened right up to a porn site. Normally I wouldn't care cuz we sometimes watch it together to get the mood going but we haven't had sex in 3 night and is was my fertile week!!! I asked him about it and he said you didn't do anything the past few nights?? seriously that what he said!!! I'm super pissed at him and he said I'm overreacting. SO LADIES AM I OVERREACTING?? What would you do in this situation
