Honestly, I don't know who you talk to. I have never tried it. I know that on AT&T phones you can check who you have been calling or texting. I don't know about any other phones though. If you feel unsafe on the phone or on the message boards, you can email TEEN-LINE. http://teenlineonline.org/talk-now/
Scroll down. You'll find it
But just a reminder, they get hundreds of emails a day so getting an answer might be a slim chance. Also, you can still try the message boards. We are a pretty understanding group, I must say.
