Dizzy spells 😣

10 weeks pregnant and I feel so weak and get bad dizzy spells so quickly! I keep eating and try to eat healthier and it doesn't seem to matter. I still end up feeling like I haven't eaten in hours and I get so weak and shakey. Only thing that got me through the weakness and dizzy spells at work today was jolly ranchers! Anyone else experience this? I'm going to see my ob tomorrow and I'm gonna mention it and see if maybe it's low iron or low blood sugar? Hopefully he can help I'm tired of almost passing out at work!
