I recently had unprotected sex around five or six days ago. Today when I went to the bathroom, there was a noticeable amount of blood in the stool. I had my period about two weeks to two and a half weeks ago so I no it's not that. I have been having abdominal cramping as well. My breasts don't hurt, I haven't felt all that much fatigue, and my feet aren't swollen.
Please tell me if I am just overreacting or if I am pregnant. Also, would it be too late to the Plan B pill?

Pregnancy won't cause blood in your stool and you won't have any pregnancy symptoms five or six days into a pregnancy. If you are passing blood and having abdominal cramping you need to seek medical attention VERY QUICKLY. Go to the closest emergency room. These ARE NOT pregnancy symptoms.

Call your dr. jessy is right, that does not sound like pregnancy symptoms at all. And even if they were, they would be the symptoms that your dr needs to know of immediately.
By the way, planned be is a preventative pill that is to be used within the first 72 hours of having unprotected sex. So yes, it would be too late to use it.
