I lost my virginity and had unprotected sex. Today is going to be four days after intercourse. On the first day of the intercourse I went to the restroom and I noticed that the toilet paper had a little bit of blood on it. What does this mean? Is it because it was my first time? Also, I noticed that I am getting hungry in the morning. Before having sex with my partner, I would not get hungry in the morning. Is this a sign that I am pregnant? I have irregular periods so I will not be able to tell if I am pregnant on that part. Also, how long should you wait to get a home pregnancy test?
