Hello, I am a 27 year old healthy female but recently I have missed my period as of three months as well as I have been passing out. I am scared to be alone and do not understand what is wrong. I have taken an at home pregnancy test over the course of the past three moths and all have shown negative. I have also gone to m health care provider my OBGYN and still no answers no one will tell me what this could be ....HELP
