So my period is five days late, and for the past few days I've been having thin milky white discharge which I usually experience before starting my period.. but earlier today I thought I felt blood coming out, but when I checked it was literally watery discharge almost dripping out. My boobs have been sore and I've been experiencing cramps and back aches. I'm tempted on taking a pregnancy test but I don't want to go buy one and then start my period. My husband and i have been trying for months now but aunt flow has always been on time. I want to wait at least a week or two more, the anticipation is killing me. Any advice?
