I am 5 days late on my period. I also had implantation bleeding (spotting) for 3 days, a week before my period should've started. From what I've read, implantation bleeding is a sign of early pregnancy. My nipples and breasts are hurting, I was dizzy for 3 straight days, I've been overly sensitive and craving chocolate... I have taken two tests and nothing... I also read about "False Pregnancies". Where we want a baby so bad that our bodies give off these symptoms without a fetus. I'm just wanting any information about what could be happening. Thank you!
