My cycle is always about 23-25 days long...This month I started on the 15 and ended on the 19. I however started heavy cramping on Satuday the 29th at about 2...didn't know what was going on because I haven't had cramping since I was 16 (27 now)...about 10 o'clock on the 29th I started spotting which was way early...and today the 30th it has turned into a light bleeding along with cramping...I have been reading on this and most say it's an early sign of pregnancy horwever I don't have any other signs of pregnancy...Is it just my body adjusting or could it be implantion bleeding? and if it is when will it show on a test?
