I am currently 18 weeks pregnant and since i was 12 weeks I have the tendancy to faint, i feel fine one minute and then the next im on the ground,but when i snap out of it i feel realllly energetic,its kinda weird. I asked my DOC about this and she said I need to get more snacks in during the day But I eat ALOT at least every 2 hours. I've heard this is normal through many pregnancies, but has anyone else experienced this? Thanks for anyone who can help.
