My girlfriend due date on her period is on July 21. We had unprotected sex on that day and ill pulled it out before I ejaculated... few hours later she had her period, what are the possibility And chances that she is pregnant? Today is aug 9 and her next due period will be on 17, she is not yet still experiencing symptoms that she`ll having a period. Help please

The changes are about medium. You used no protection, and pull out does not work since there are plenty of sperm in early fluids.

Since it was same day as period, her having that period does not mean she is not pregnant, it will be this period.

So now you have to wait, if she misses this period, she has to wait till she is 2 weeks late, and then test using first urnine of the morning.

Anyitme there is penetration with the penis, even with protection, pregnancy is possible, no birth control is 100 percent.
