hi im a 21 yr old female i weight 155 have two kids about two weeks ago i starting craving food but couldnt keep nothing down. At first i thought it was a bug and theni thought i might be pregnant I also lost my taste buds and couldnt stand the smell of alcohol beverage which was really weird because 2 weeks prior i had drank for my birhtday and i was fine with it. I started getting getting metallic taste in morning and nausea and minimum exercise i get tired. Two days before my period was due i started spotting and got brown discharge . Now i have headaches and blurry vision ..what could it be?
