Um tmi but I need help.... 😭

So this is kind of embarrassing for me lol (hence the anonymous post) but ever since around I was 15 weeks I noticed no matter how much I brush or use mouthwash or even gum... My breathe still smelled weird. As if my stomach were empty and I had not eaten. It happens all the time even after Meals. Im so worried it might be something wrong.. Has anyone experienced this before? I never had breathe issues before being pregnant. 😭 help
