my sister in law said her temp is 99.2 and has been running that all morning.. she is 9dpo.. she said she took a quarter of a sleeping pill last night b/c she was so tired but she couldnt fall asleep.. she didn't want to take the whole thing.. she said this morning shes dizzy.. and when she goes from a sitting postion to a standing position she gets really dizzy and her vision goes blurry for a minute.. she said she feels 'hot' and her temp has been running 99.2 all morning.. shes a little nauseous.. i told her it sounds like she is getting the flu to me.. does any of this have anything to do with being possibly pregnant?
