Me and my husband have tried to concieve over a year now and I had one miscarrige in febuary. This month my period was 6 days late with little spotting then my period started withouy cramps or anything and have lasted for 6 days... FYI when it was late I started feeling nausea and tired and just craved for energydrinks. When my period came I still feel all of these things and feel like I will throw up all day. What can this be? I need some help please
