Is painful palpatations, breathlessness, dizziness, and confusion "episodes" normal for anemia?

i am 20yrs female 5ft8in tall medium build and weigh 152lbs.... if that helps anything... i am being tested for anemia... i have always had the clic symptoms: pulsing dizziness(like ripples in water, not spinning), nausea, breathlessness, racing heart, random bruising out of no where,joint pain, problems concentrating or remembering current events, clumsiness... but lately, within the last month they have gotten worse i went to the Dr and he took some blood for testing and told me to come back in two weeks, he didnt seem to concerned.... but since then my lil 'episodes' have been closer together first my heart starts racing and i get winded all the sudden as if i just ran two miles when im actually not execising... then the dizziness hits me and many times i get confused during these episodes i dont understand what people are telling me and sometimes not really sure where i am.... since it started bothering me at work ive been worried plus these episodes are starting to become painful..... and they can last up to 30 minutes i have had 5 of these episodes today alone.... is this normal???
