Hello,
If you took birth control pill regularly, then 10-15 min late taking does not reduce efficacy of the pill. It prevents unwanted
pregnancy more than 99%. Here, chance of pregnancy is very much less. So, don't be worried.
Bleeding after sex occurs due to
blunt trauma or uterine polyp. Old endometrial tissue or
pelvic infection may lead to brown discharge in association with vaginal bleeding. Just maintain your genital hygiene properly.
White discharge and cramp prior to commencement of period is quite physiological. It occurs due to
progesterone hormone and PMS is mostly associated with that.
Here, you would wait for coming period and do one home pregnancy test immediately after missed period. One
blood test for beta-hCG is required to confirm the same. Kindly, consult with gynecologist after doing the tests.
Practice safe sex. Good luck.
