So I ovulated expected on Sunday 11th August , 11 dpo I had some cramps and back pain and 12 dpo when I wiped it was some brown spotting , for the next two days after that I had light bleeding mixture of pink blood/brown & red. Very light and watery when I wiped. Iv had back pain , sore head and cramps. Today it has stopped and I bave nothing. So it lasted 3 days max. The last three months my period has always came on the 30th of every month so this month my periods came nearly a week early. Do you think I should be worried or could it be implantation , only thing putting me off that is some of the blood was red.
