I am 17 years old and my last regular period was April 29th. And may 25th me and my boyfriend had unprotected sex and he feels like he nutted in me. I was suppose to get a period four days later ut it did not come until the 7th of June but was extremely short and ended the 9th. Today is now the 10th and STILL NO PERIOD .nor did I get one the last month on the 29th.WHAT IS THE CHANCE THAT I COULD BE Pregnant? AND HOW LONG WILL IT TAKE UNTIL IT SHOWS UP ON A HPT?

You could take a HPT now.

Anytime you have sex you could become pregnant. Unprotected sex means you have a much greater chance of being pregnant now.

Even with protection there is a some chance and with no protection it gets higher.
