I had the same early in my pregnancy I found carrying a biscuit and a bottle of water everywhere with me helped alot x

@zeld, thank you, i hadnt even thought of that, oops! 😊

Probably just fluctuating hormones and your blood volume increasing. as long as you are hydrated and eating plenty you are probably ok. if it doesn't resolve best to see your gp for a quick checkup just to make sure
