Embarrassing

So I'm embarrassed about this but, I'm still going to ask and tell. Since I've become pregnant I notice that sometimes I smell a blood or a fishy odor. Especially on days where I'm too sick to shower right away and when I use the bathroom. I had exams and blood work, but everything came back normal. I thought it was BV at first but it's making me self conscious and irritated. Has anyone else experienced this? All I drink is water, maybe I need to stop eating meat? Idk. Hopefully one of you can help.
