Preeclampsia?

I have less then a month left of my pregnant and it’s getting so hard now. And I’m worried that I might have preeclampsia. Or idk if what’s going on is normal I feel short of breathe it’s hard to walk my ankles are swollen and purple I have headaches all the time. This is my first and I just feel like complete shit and like I can’t do nothing and idk what to do.
