Anxiety sleeping next to my husband

I am pregnant in my first trimester and have developed Anxiety sleeping next to my husband. There is is absolutely no reason for it. He’s a gentle caring man and never makes me feel bad for getting up a million times a night to go to the toilet or take a bath ect this isn’t my first pregnancy either. I’ve not had this problem before. I will fall asleep and jolt awake panicking. But when hubby sleeps on the couch, and it’s just myself and our 2 year old, i sleep like a rock. I’m so confused as there seems to be no logical reason for this. As my 2 year old moves more than my husband (we co sleep) so it’s not him moving etc. Does anyone else experience this?
