i had sex two days after my last period and was a little nervous on becoming pregnant so just in case i took plan b one step within 24 hours of having sex, about a week later i had very light bleeding for a couple days although i already had my period that month it is now november and i haven't received my period when the first one came in november, could the bleeding i had count as a second period to make me not pregnant, and therefore the next one will come around then? i'm not experiencing pregnant symtoms either, i have cramps though, has anyone had any experience similar, and was not pregnant? please share your experiences!
