so i had sex with my boyfriend on valentines day. it was unprotected, but he did not go inside of me! i was still worried about pre cum- so i took plan b within 12 hours. i got my period about a week after, i don't remember if it was light or heavy but i just got my period like 3 days ago.. 3 months later and its very light like really light! i took a pego test and it said no. it was first response also.. should i be worried that I'm prego?
it should not stop it just should be a lot lighter
