Low blood pressure normal??

I was making my daughter breakfast and started feeling really weird my heart was racing my head started feeling really odd and I found myself grabbing onto the stove to stay up I felt kind of out of body and like I had no control over what was happening it was really scary I went to go sit down and I can’t stay up without feeling like this now my blood pressure is 90 over 55 I’ve never had a reading so low I had hypertension with my daughter and had to be induced because it was harming my organ function never low blood pressure though? Is this normal?
