How likely is it that i'm pregnant?

[bluebear18]

I started my period last month 4/28 on 5/4 my boyfriend and i had sex and the condom (spermicidal) slipped off inside me. About 4 hours later i took the morning after pill (progestin only one step, Take Action tm) we also inserted some spermicide (i know its only effective if used before intercourse but we used it to kill any sperm that may be in the vaginal cavity still). I bled from the plan b 5 days later a decently heavy flow for about 3-4 days. my period was due yesterday but is still not here yet. should i be worried that i'm pregnant or is it more likely that the plan b is throwing my cycle off?

When I did plan b a few years it completely through my cycle off, so it's probably the plan b.

I think its the plan b throwing your cycle off to be honest. Take a pregnancy test to be 100% sure
