plz i need help

Yes there is still a chance. I would suggest going to the doc and explain the situation. They can do a blood test that test different than the urine. Using the blood as a sign is never a definite. People have been pregnant and still had a period and others period has strangely stopped for sometime but they were never pregnant. The only way to be sure is to be check out my a professional.

It is very unlikely that you will get pregnant from period sex unless you have very short cycles. There are also many things that can delay your period: stress, weight change, exercise, change in sleep pattern, general health problems etc.

Normally you cannot get pregnant during your period. Your period is when you are shedding the lining of your uterus and preparing for the next egg. If you have a 28 day cycle (the average cycle length), that means you would have ovulated on October 11th. Also, the emergency contraception pill does have side effects. It is a mega dose of hormones and it can mess up your period. It can be shorter, longer, lighter, heavier, early or late. If you have taken 2 pregnancy tests, I think they are a good indication that you are not pregnant. Also stress and worrying can delay your period. Good luck!
