Confidence, while pregnant .....

My husband and I have been together for a little over five years now, he is the love of my life! We already have two beautiful boys together and im currently pregnant with our third, lately I just haven't been feeling pretty I've been in the dumps and this usually happens every time I get pregnant but its really getting to me this time around, my husband isn't one to like other women's posts or pictures or even hang around over women but lately he has been and its been making me feel even worse. And every time I bring it up to him he tells me is shouldn't matter and that it doesn't matter but it does to me especially because he knows I've been feeling like this. I'm not sure if its even worth another conversation especially if its just going to make things worse I want to get over it but for some reason I just can't, I don't think he is cheating on me or anything I just kinda wish he would put more effort into making me feel better about myself instead of liking other women's pictures and hanging around this women I don't even know cause it just puts me down more.

Update: this random woman is his friends sister, just bothers me because 1 I've never met her and 2 she pops up in conversation all the time, I guess shes hung out around there job after work and even taken my husband home once. And the only thing I know about this woman is that she's done drugs with my husbands mom... So I don't trust her already

#2 he claims that he accidentally likes these photos on Instagram which is possible but the pictures are selfies of women we know personally (one I personally really don't like) I feel like my hormones are blowing things up but I don't like the not caring about my feelings, but I do feel like him liking these photos makes me look bad... Like I'm not good enough for my husband cause I know other people look at things like that

Update #3 we talked and it got spun out into me not trusting him and he should be able to like other women's photos without me getting so upset about it, and he isn't allowed to talk to any woman ever he deleted his Instagram and he won't even hear me out he doesn't want to talk to me and doesn't think I should blame the pregnancy for how I'm feeling right now.
