i went through two pantiliners with some actual dark blood but nothing like a normal period
for me. as the day has continued i have put on a pad
and i can feel blood flow, and it is a lighter red color, accompanied by cramps in my uterine area and some minor lower back pain. i have always had these symptoms on my menstural cycle but im not due for my next period until the end of next week. could i be pregnant and need to see a doctor? or is this a heavy implantation bleeding im experiencing.
