Accidentally saw porn of my partner phone that he watch

Maybe I'm over reacting here.

I.know my boyfriend watches porn especially round that time of the month anyway I had to use his phone and I ask first to use to I need to Internet to find a recipe as I didn't have my phone and when I went to use it I had to open up another tab, we'll delete one as he had all the tab up and when I did I show about 16 out 18 tab that was porn. I think war hurting is that we r trying to have a baby and since coming off my period we had sex like twice and it been two week since I finish. And at the moment I feel like maybe that reason why we haven't had lot of sex since I finish because maybe he watching porn more. Please tell me I'm over reacting here

I told him maybe close.down some of those tab he was like wat u doing going though my Internet and when I explain what happen he was okay about I just to laugh it off but yeah
