Jealousy

I need advice. I have been with my SO for 2 years now and just recently began ttc. However my jelousy is killing our relationship! Snapchat and Facebook drive me crazy. I don't have reason to believe he's doing anything wrong but I can't shake the feeling that he's cheating on me or talking to girls behind my back. It's gotten to the point that if he is being really sweet I automatically assume he's feeling guilty 😭 I even get angry if he looks at another woman which I know is not normal! I've had pretty bad relationships in the past and my trust is shot to begin with. Will I ever be able to get past this feeling?!
