I got my period on the 26 last month it was late to start off with but it wasnt normal at all. When i wiped it was pinkish color and very little blood. Well later that night when i went to change there was nothing on the tampon. What could that mean? My lower back starts to hurt all the time. Sometimes my boobs hurt. My lower stomach hurts and i feel like i gained weight or i just been bloated i dont know...help...
