Im 22 and was meant to be on my period around the 12th still no sign just pinky discharge then brown spotting I'm never late what could this mean?

Its not uncommon to be 2 days late on a period ,but the discharge could be the result of imbalance of protective germs. This can be caused by an antibioic or medicine you were taking. When did you last have sex? Was protection used?

Im never late though never have been I'm not on any medication and no No protection has been used x

In the medical community 2 days is not considered late even for the most regular of women. Every once in a while we can be late or even miss a cycle for no reason whatsoever.

If you are still late in another week it would be best for you to take a HPT using first morning urine.
