Shortness of breath and dizziness at 16 weeks 😥😥

♡ 𝓚𝓪𝓽𝓻𝓲𝓷𝓪 𝓵𝓸𝓾𝓲𝓼𝓮 ♡

So I'm 22 and 16 weeks pregnant and this last week I've noticed that if I stand it feels like the room is spinning and then I find myself losing balance. I still have morning sickness unfortunately but I just took a shower then and my chest felt really really tight I had to really breath in and out to feel like i was getting enough oxygen but I felt lightheaded again.

Is this normal ???
