My boyfriend doesn't get it... Maybe TMI

my boyfriend just doesn't get it... He really really doesn't. My body is changing a lot already (13.5 weeks with first) and I'm feeling so insecure about it ... The weight gain and just everything! When I complain about it to him he doesn't reassure me ... He just tells me I should go work out more if I feel that way. He also gets so disgusted by all the extra discharge... Which makes me feel even more self conscious esp during sex which we barely have anymore . He even told me I should do kegals because all the extra wetness down there makes me feel less tight....All of this is making feel really insecure and doesn't help that he likes all these girls pictures on Instagram that are like half naked. I know it's just Instagram but still.. I can see it! And it makes me even more insecure. Ugh.
