So I've been reading about some people's pregnancy test showing up Negative and then they end up finding out when their 15weeks pregnant that they're actually very pregnant because of the low levels of HCG in their bodies taken every other week.. my mom had this problem with her pregnancy with me and my siblings... I'm not sure if it's just me but I have ALL the symptoms from : Nausea(vomiting),Headache,Body aches,Hot flashes ,Sore breast, darkening of my areolas ,and my pelvis area has been hurting . Any advice ?? Any opinions??
