Husband thinks I’m oregnancy

I have had two miscarriages with my husband. And today this morning he says I think your pregnant. I do have some signs but I’ve been hurt by those two loses and I don’t want to get my hopes up I took a test three days ago negative. Why do you think he’d say that?

The only things I have are gas back pain nauseous and I had more the last time I was pregnant. What do you think? And why do you think he says that he thinks I’m pregnant. ??
