<human>: Can you provide a brief rundown of the text in within 3 sentences?

We've been dating for about 2 years now. For the past six weeks or so we haven't seen each other much because her sister recently had to have a hysterectomy. I thought this was going to be the cause of us breaking up, but we finally got together and things seem to be back to normal. However her sex drive is way up. 

During the two years we've been dating I've never used any protection. She has always claimed to be on the pill and I always trusted that she was(Disclaimer: I do know that its not foolproof and that it was stupid). However now something feels...different. I just don't have a good feeling about it. We're meeting Saturday for a date and shes made it clear that she wants to get laid and I don't know how to bring up after 2 years that I want to wear a condom this time. 

I am not financially stable enough to have a kid so it was stupid of me to have risked it as much as I have, but we've recently had discussions about how shes worried her parents will never have grandchildren and that her biological clock is ticking. This issue is compounded given her sisters recent medical issues. 

I realized this all probably sounds juvenile and stupid, but I love her and I want to marry her. I am just not ready for children and I don't know that she would be honest with me about her intentions.
<bot>: I'm worried my girlfriend is trying to get pregnant and I've never used a condom during sex with her and I don't know how to bring up that I want to without starting a disastrous fight.
