My period is 8 days late.i had sex but the boyfriend did not ejaculate .i had my period after sex but next moth (this month) my period is late.i had a rare pink period and now i have brown . is it possible that i'm pregnant?

If you had sex since your last period, you could be pregnant, your boyfriend not ejaculatiing notwithstanding. Do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. Wish you good health! If you do not wish to be pregnant, use contraception all the time, every time.

Your statement is not clear. If you had a regular period after sex, you could not be pregnant. If you did not have any sexual encounter after the last period, pregnancy is impossible although your period is 8 day late. If you have any doubt, a urine pregnancy test at this time can clear any concern.
