So today, me and my partner had unprotected sex and about 6 hours later, I have noticed that in my panty liner there was a very small but noticeable amount of blood in my vaginal discharge and then when I went to used the bathroom and looked, I also say the bloody discharge again but you could really see the blood, like a light shade of red mixed with white. Could anybody help me out? Is this something I should consult my doctor about?
