I had unprotected sex both yesterday and the day before, then I woke up this morning and when I wiped there was blood, I usually have a normal flow but this is very light as of now and its also a week earlier then expected... Could I be pregnant?

You wouldn't be able to determine pregnancy so soon after intercourse. If you have indeed become pregnant from the recent sex, the egg would still have days to go yet for implantation, which is when some women may notice some slight spotting/bleeding.

The bleeding is likely due to either the recent intercourse, which sometimes happens, especially when you are close to starting your period, or your period may start a bit sooner than your norm.

Wait and see what happens when you would expect your period normally. If no period for this month, try a pregnancy test.
