Concerned 30 weeks pregnant

Lately I’ve been having some shortness of breath but early this morning I woke up at 6:30 am feeling like I couldn’t breathe, I was able to cough it out but it was very painful and almost threw up. I’ve also been experiencing white spots in my vision and some light sensitivity a few times a day. And I’ve been suffering with bad headaches since the beginning of my pregnancy but they’ve gradually gotten worse. I’m lucky if I get a couple days without one. I haven’t had morning sickness in a long time and the other night I woke up suddenly at 4:30am and had to get sick which is not normal for me, and I’ve been experiencing bouts of nausea since then. Just wondering if you ladies have any advice? I don’t wanna go to the doctor/hospital for nothing but I’m starting to worry. My blood pressure hasn’t been a concern so far so I don’t think it’s preeclampsia but I’m not sure if this stuff is normal or not, first time mom 🤦🏼‍♀️
