Shortness of breath

M
I'll be 15 weeks on Saturday and for the last month I've been having shortness of breath and my heart has felt like it's beating fast. I feel like Im never getting enough air, kind of like how I sometimes feel when it's really humid out in the summer or the few times I've had a panic attack in the past. I'm going to tell my doctor next week when I see her but does this happen to anyone else? I feel like it's way too early for me to be feeling like this but I have been under a crazy amount of stress lately too so idk
