Okay, so I'm 15 weeks today.... Well for the past week or two, I've been getting really bad hot flashes to where my shirt is soaked, while that's happening I get really light headed to wear I collapse, and my body gets so weak and shaky... I get so dizzy I can't even see the cash register at work.... I feel as if this isn't normal and it freaks me out. Because it makes me so sick for the rest of the day...
