Blood in diarrhea /I think stomach bug /15w pregnant

I've had bad nausea and vomiting from the start. It seemed to just lighten up a little bit in the second trimester. 3 says ago I think I caught a stomach bug that my nephew had and I haven't been able to keep a lot of food down. Yesterday I started having diarrhea and vomiting. Today I was able to keep breakfast down, but threw up since then. I had diarrhea a few times today but this last time there was a lot of streaky blood mixed in with it. It was regular red not black or brown or dark. Is this a problem or just my bowels are tired or something? I can't seem to find anything online because nothing I can find is specific enough to fit pregnancy and stomach bugs and bloody diarrhea. Husband is not concerned but he's a little on the "you're fine not a problem" side (I think he'd say that if I was run over by a car) and I don't want to call my mom because she'd think I'm dying and want me to go to the hospital over nothing. Has anyone else had this problem?

Also: I don't throw up just water I can keep that down
