Blood pressure low? Feeling faint?

Hey ladies,
In 8 weeks and sometimes feel so light headed. Or sometimes it feels like I can't catch my breath. I know it's normal and I try not to panic but it's not a pleasant feeling. I've been trying to drink lots of water. Anyone else experiencing this? Any tips?
