IMPLANTATION BLEEDING ??!!

Amanda
According to Glow af was a day late. I passed a weird "blood clot" the first day. Then after that, what I thought was af got REAL light in color as well as amount and cycle length. The last couple days were rusty brown. We had sex every day I was fertile and I've had headaches everyday the past week. Today I threw up. Should I take a hpt? If so, when?
