Jealousy

Last month I had a chemical pregnancy and from finding out I was pregnany until about 2 weeks later I was crazy jealous of who my fiance was with/talking to. I even went through all the pictures on his laptop from before we were even together to get annoyed at and i looked on his phone when he was in the shower. I am NEVER like this and know I can trust him 100% I felt like I was going crazy! I am assuming it was the hormones and I am just hoping when I get pregnant again I don't turn into this jealous psycho! I was even mad at him for going to his male friends house when I know they work together and were working! Has anyone else experienced this when they arent normally like that?
