It's not possible to be pregnant AND have a period. It's possible to have light bleeding or spotting in early pregnancy, which some women mistake for a period- like the poster above - but this is not a period.
You're friend isn't/can't be pregnant. 2 days before the start of period isn't a women's fertile time, and although sperm can live inside for 2-3 days this will likely be washed out along with her period, so pregnancy isn't possible here.
Im 19 weeks pregnant and i had my period the first month i was pregnant......but its not like a normal period its light i didnt think i was but effective enough i was already 6 weeks when i found out :) dont mean to scare ya but theres always a possibility. Remember it takes 10 days for to become pregnant.
She isn't pregnant if She had her period
