Hello. my question is i had in protected sex using the withdrawal method during my fertile time. my period came a week later and continue for 11 days then it stopped and started again. what do you think is wrong?

The rhytm method: is actually ineffective: sperm is carried in the male pre-ejaculation fluid and it only takes 1 sperm cell to have someone calling you "Mommy"- try using condoms, spermicidal foam, gel, sponge or vaginal eggs- do a home pregnancy test and discuss definitive BC with your GYN. Your bleeding may be hormonal or from a spontaneous abortion.. Call today!
