I have always had a normal heavy 6 day period. this month it came very late(1 week) but i only bled for one day then light pink spotting, am i preg?

Maybe not, but...: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period or after having a "weird" period.
