I think I figured it out! I wasn't taking the iron pills that was prescribed to me because I was afraid of any adverse effects it would have with the high blood pressure medication I was taking. Once I started taking the iron pills, the headaches stopped, but now I have spells where I black out. I am still conscious, but can't see anything for a few seconds at a time. I called my ob/gyn 4 TIMES (because as I said before I am 3 month pregnant) and they NEVER called back. I am trying not to break down and go to the emergency room. But it's looking like I may have to anyway. So could it have been the low iron wreacking such havoc? I am thinking of changing doctors too. I hope I'm not too far along to change now. Will keep you posted.
