Is she lying?

This is the story. My girlfriend and I have been going out for about 2 months (she's 15, I'm 16) We've had sex only ONCE. But I can assure you, I was wearing a condom. Let me tell you a little about her, she's really flirty towards guys. She even does STUFF to them in front of me! And by stuff I mean kisses them right by the mouth. She tells me they're friend kisses. She let's guys touch her. Anywhere! And she just laughs. Now she's telling me she's pregnant. With my baby. Is there a chance it's mine?

no there aint no chance in minda if you were a condom and it did not break you should be fine she sounds like a lil busty anywayz leave her ass alone tell her you dont honore all that sh*t! sh*t I would

If no semen was near her vagina and the condom was intact then no I don't believe she could be pregnant by you. Maybe she made it up, she sounds like she likes attention. It could also be possible that she was messing around with someone else. If she is so unfaithful to you and completely disregards your relationship right in front of you, I'd forget about her.
