I don't remember anymore.

Hi everyone.

I'm a 15-year-old guy. About 1 to 2 months ago, I had sex with my girlfriend. The condom broke, but she got her period a month later (I've got a scar from the shock and fear). Now, 2 months later, I had sex with my girlfriend again, right after she had been on her period for 2-3 days. Now she has some sharp pain in her side (let's call it a side stitch) and also abdominal pain ABOVE the womb, as she describes it. She also has a sort of menstrual pain in her ovaries. But she also has a LOT of stress. And now, as a worried boyfriend who has a bit of a scar, I'm naturally very scared that she's pregnant. But now I have a few questions. Is it all in my head because I have this rotten feeling that's eating me up inside mentally? But best people, now my question:

Are these pregnancy symptoms or not?
Or is it all in my head because of the scars?
I know that the abdominal pain comes from stress because when she's distracted, the pain goes away, and when she gets panicked, the pain gets worse. Her mother had that too in the past (our parents know about the broken condom). But above all, I'm wondering very simply: What is and what does that menstrual pain in her ovaries do? And is she pregnant or not?

I've been feeling like crap for a week now, and I can't even sleep (I panic easily and can't handle this kind of thing). I also think she's pregnant if she's, say, feeling flu-ish.
In short, I want to know what you think.
Personally? I don't know anymore. I have no interest in anything. Pizza? No thanks, I'm not hungry this week. I've lost 3 kilos. I know I should eat, but I just can't get it down. Fixing scooters, which I usually spend day and night on? No thanks. The only thing I do is go to my internship and try to make something of it. I also told a friend recently. He said: "Boy, you always have bad luck." I said: "Well, what can you do? It is what it is." But I don't know what to do about it. No, I get it. He said: "Bram, I've been getting by for 15 years." Even though I have a crap situation at home, I'm getting by now. Well, best people, I can tell you, I'm not so sure about that anymore. I'm really driving myself crazy just to avoid having to go home. But anyway. You know my worries and questions. I hope I get the responses I hope for, but well, they also say time will tell. But when you feel like crap, it seems like every second lasts an hour, to put it that way. It's exactly half past 2 in the morning. Why so late? I just can't sleep. I'm literally falling asleep from misery, so I thought, well, maybe I can do something. Maybe it helps, maybe it doesn't, we'll see then.

So best people, I hope to hear from you soon if you want to email me. Here's my email: [email protected]
Well, see you later.
