I feel very tired just recently, and not just that, also a feeling as though I cannot catch my breath. This only happens if Im standing up too long... Along with that, I'm getting a 'weak' type feeling at night, I dont know if this is the same as fatigue, but it's as though I havent eaten enough sugar, or I desperately need a cup of tea. Is anyone else going through this? They say the 2nd tri is suposed to be the best, but in the last few days I have felt nothing other than exhausted.
