so my boyfriend and i had sex and the condom broke. as soon as we noticed it had broken we went out an got plan b which i took. i had just finished my period 2 days ago. my perion normally lasts 5 days. about 4 or 5 days after taking plan b i started bleeding again and had basically had another period for 5 days. is this normal? does this mean i am not pragnant? or does it mean that i am pregnant? or does it mean anything? please help
