I have been trying to get pregnant for a year and 3months now. my period is normally 6 days every 28 days. I got my period on time this month on Tuesday but what's weired is that first 2 days and the beginning of 3rd day it was normal after that i don't see blood on my pad only when i wipe is this normal.. my period is normally 6 days. I'm just worried if there's a problem and been trying for pregnancy.
