Ok I had unprotected sex, on the last Sunday of January, the again the first three days of February, the on the fourth day of February I had started what I thought was a period but it quit like three hours later then nothing till around the 14th then I started bleedin again. Could I still be pregnant?

It's possible, but you wouldn't have a period if pregnant. Some women do, however, have some spotting or bleeding in early pregnancy.

You could try a pregnancy test, or wait and see what happens when you would expect your period for March. If no period, or it is off again, try a test at that time.

Since there can be various reasons a cycle may be irregular, if you have two in a row, you might want to consider seeing your doctor about possible causes other than pregnancy.

It is possible to have a period and be pregnant. Go to your doctor or have a hpt done (:
