I DONT KNOW IF IM PREGNANT, I FINISHED MY PERIOD 3 WEEKS AGO AND HAD SEX 2 DAYS AFTER, THEN I GOT MY PERIOD LIGHTLY AGAIN A WEEK AFTER. BUT NOW I CANT FALL ASLEEP AT NIGHT. COULD I BE PREGNANT OR IS MY PERIOD CONFUSED?

[b]if its spotted and only lasts a few days get a test.

That light period could have been implantational bleeding..also known as spotting which is cause because a fertilized egg is burrowing itself into your ovaries. Usually implantational bleeding is lighter, red brown or pink in color, and the duration is shorter. It might be wise to just take a home pregnancy test and maybe take more then 1 for accurate results.

yes you could be pregnate but you could of had a period confusion if i was you i would go to the doctor
