The last period I had was jan.8-12th , since then I've had sex on the 26th and was suppose to get my period on the 5th of feb, I am late but got it the 17th of this month... n I had light cramps with a light dark flow then later in the night it was bright red.. and today its lighten up am I pregnant?

Wait and see if you get a regular period or if it stays light and then stops.

If no normal period, you can try a home pregnancy test with the first urine of the morning, it is possible.

So far its staying light and not flowing so heavily anymore
