Persistent dizziness in early pregnancy

Hi all, I have been feeling dizzy since week 6. To alleviate my dizziness, I had to lie down (sitting down just doesn’t work). With this dizziness issue, I could barely work. However, checks from GP and gynae shows everything is normal. I don’t have much nausea and vomiting too. Anyone experiencing/experienced similar symptoms? How do you cope with it? Would it get better soon? #advice #firsttimemom #worried
