All right, I've been really stressed of late over many things et cetera and I've been having irregular periods. My last one was two months ago. My mum thinks it's because I've been fooling around and got pregnant. I'm still virgin, but whatever I do, she doesn't seem to believe me. We don't talk anymore, it's more like shouting. I've been able to talk to my dad somewhat, but he keeps getting off of the topic, he's really trying to stay out of it, I guess. But it's really getting on my nerves now. I can't really handle it, and she's been trying to drag me into the doctor's office, just to prove that she's right. I don't know what to make of this anymore. I think I would know if I had had sex, right? I have no idea of how to handle the situation and could use a bit of help.
