Extremely lightheaded?

I’m 10 weeks 4 days pregnant. Here lately I can’t do much of anything without my heart taking off. I then get lightheaded, and so dizzy to the point where I get nauseated again. It’s so upsetting because I feel useless. Whether I’m carrying a load of laundry to the living room to fold or just doing some basic cleaning, I can only do it for a couple of minutes before it hits me. I have never been diagnosed with high blood pressure, but in the past at the few dr appts. I attended, it was rather high. We always chalked it up to me being nervous, however.

Is this normal? Has anyone else had this issue?
