Postural hypotension: Followed by syncope (fainting). This is due to a chaotic autonomic (automatic) nervous system and is directly due in most cases to vitamin deficiency from a lousy diet, particularly all the sweet junk. It is common in the U.S.

Autonomic insuffic: You have symptoms that suggest a problem called autonomic insufficiency. This is common in young women. Essentially the brain can misread the signals being sent by the heart and blood vessels and cause the pulse to go fast (or slow) and the blood pressure to fall. Pregnancy makes this a lot worse. For now drink lots of fluids and lie down at the first sign of symptoms. You should see a heart md.

Get evaluated: You need to seek professional evaluation. Perhaps a neurologist would be a good start. You may also want to be evaluated for an irregular heartbeat.
