I have been trying to get pregnant.my period isn't due for more 2 weeks.I feel breast sore and tenderness.I also eat more and have cravings and frequent headaches.my lower back pains and have a mood swing too.is it too early for the symptoms or can I be illusioning it.I am desperate and just want to know if or not am I pregnant.are there any symptoms of pregnancy that you can feel even before you miss your period?
