Crazy wife . .

I was going through my husband phone because I’ve been getting this gut feeling something off . I went through his Instagram I’m not very tech friendly so on the search main page there was a bunch of videos and pictures of half naked girls and shaking their ass . My question is I have an Instagram I rarely get on but my search suggestions are not like that was wondering if maybe his been looking/browsing at naked girls on his page ? I know I may sound crazy lol but I’m 31 weeks pg and my hormones are all over the place .
