That's the thing. She hasn't had any symptoms except headaches. No delayed or missed period. All periods were on time and lasted 5 days. Doesn't this rule out pregnancy? Nausea lasted only 10 days and it was probably because of the food poisoning. Morning sickness nausea lasts more than 10 days, doesn't it? Getting a pregnancy test will just freak her out. And it's very hard for teenagers to get it where I live. That's why I ask questions here otherwise I would just get a test. I understand you cannot tell but what would be your educated guess? When does abdomen starts to get bigger in pregnancy?
