Hey I m nearly 5 days late for my period, I m getting terrible lower back aches, alot of pressure, cramping in my stomach I feel like my period is going to start but it won t come, my appetite is gone, I m so dizzy and exhausted, I have blue veins around my breasts and mostly around my nipples, I just feel a little strange. I took a home pregnancy test today and it was negative, so why do I have a feeling that I m still pregnant. Maybe it was too early to tell. Please give me advice. Thanks
