What does it mean when trying to conceive and two days later you start having brownish blood when you wipe and the next day it starts turning pinkish orange?

it is probably implanation bleeding, it usually happens around 5 days after possible conception though it can happen earlier or later, implanation bleeding occurs when the fertalized egg attaches itself to the uterine lining of the womb, and that can let off some bleeding, implanation bleeding isn't a threat to the baby, but take a test in a few days to find out
