Physical symptoms after miscarriage

I have just had my fourth mc. Bleeding heavily but not severe. The one symptom I can not figure out is this " dazed" feeling in my head. Having trouble focusing and its almost a dizzy feeling. :-/ is this normal? Thinking cuz I've also had blood drawn 3 times this week plus I'm bleeding?
