yeah ngala it can drop suddenly and that will cause u to feel dizzy as well as if its gone too high u will feel dizzy too.. iron is also a good point i am currently on iron injections due to severe iron deficiency deffinately something to get checked out coz if it is iron and u lose blood during birth it will go lower making u feel worse or need a blood transfusion if u dnt sort it out... its probably nothing serious but i would def go to the dr just in case and incase there is something they can give u to stop it i know stemetil is a class a medication and fine to use in pred that stops dizziness might be something to consider if ur getting it that badly.. hth all the best
