am i pregnant?

Ni

so my boyfriend and i had unprotected sex after my first week of starting the pill.

because we were stressed the pill hadn’t started to work i took a plan b. i continued taking the pill right through and intentionally missed my period.

after i was a week late for my period my boyfriend and i took a two tests and they both came back negative. i stopped taking the pill 3-4 days ago and today i’ve experienced cramping with no period. could i be pregnant?
