my husband and i have been trying to get pregnant for over a year now. This past month i had light pink bleeding 5 days before my expected period ..it wasn't enough to fill a tampon only wore a pantie liner and it didnt fill that it lasted for 2 whole days. my period is now 3 days late. i have taken 3 tests and the were all negative.I have been feeling exhausted, hungry and very thirsty all the time. i've been experiencing headaches and cramps and cramp like pain in my lower back.Also frequent urination and my breast are tender and feel sore at times and full. my husband tells me theyre bigger. im very bloated. im frustrated and confused
