light headed,dizzy,fuzzy eyes,sweating,hot and clammy,very breathless,ears going deaf then a hissing sound. hi i was just wondering if anyone is experiencing this. i had it with my 1st pregnancy,my 2nd was fine but it has now started in this pregnancy. iv had my blood pressure checked aswel as my iron and vitamin b12 and all is fine,very slightly anemic but dont need medication. i seem to be fine sitting down,walking about but all kiscks off when im stood up,standing still? i just dont want this pregnancy ruined by it. any advise would be great thank you x
