8wks && not wanting to be touched!

So does anyone else have this problem or has had this problem..I use to love being with my so , I loved to cuddle and all that good stuff . But since I found out we were expecting its like I'm grossed out by him , even if he rubs his finger across me I instantly lose it , like why are you touching me !! I don't like being this way and I'm sure it's just my anxiety. I constantly reassure him that he's done nothing wrong it's just the change I'm going through , is there any tips you guys can give me to become calmer, I also suffer from bipolar depression, and I just rather be alone more then anything. but he doesn't understand that bc this is his first child and he wants to be there for it all . I really feel like I'm pushing him away😓. Help please...
