<human>: Could you distill the essence of the text into 1-3 sentences?

Even though we used a condom AND I "pulled out" every single time, my girlfriend is late on her period. I understand pregnancy may not necessarily be the cause,  and since she is young and has only been on her cylce for 8 years, she could have an irregular period or two. She has also started intense excersise lately, which could be another cause. But I'm looking at every possibility. 
The reason why I'm posting here, is because if she is pregnant, and she and I decide to keep it, I want to be there, and I want to be a good father for this child, and a good partner for my girlfriend. So my question is... how? What can I do to be a good parent? What can I do to help support the three of us if I'm incapable of getting a higher education past high school?
<bot>: Girlfriend and I are both teenagers, could be pregnant. How can I help make this work, if it comes down to it?
