Back In January I Had A Pregnancy Scare In Which

Back in january i had a pregnancy scare in which the contraception being used failed and i ended up taking plan b pill within the 72 hr time frame. Not even a week later i got my period which definitely relaxed my mind. Then about a week after that i got my period again. Now its march i was due for my monthly cycle on the 3rd and i still haven't gotten it.
