Well this month Jan. 4th, 2013 i spotted for 2 days and bled heavy for 3 days. My period is normally heavy the whole 5-6 days. Ive gotten really bloated, ive been getting really really bad headaches , heart beating faster than usual. My last normal period was dec. 1, 2012. Its been a little hard for me to breathe stomach has been feeling really weird i took home pregnancy test it said negative. My question to you is, could i be pregnant? And why is this happening?
