So I been confused recently about my body changes, my ''monthly '' time was due on the 10th of December and was four days late, but it was lighter than usually and had increased hunger before my period was due! Normal but it felt different! I took one first response early test and came back neg. I took another one the day my period was due . came out neg. Than finally four days later it came but it was lighter than usually! Now I have loss of appetite and headaches and fatigue ! Could I be pregnant and go buy anyother test? Someone that had the same problem please tell me asap
