Yeaht this 问题 really should have some better details... like for instance have 你 even had sex? If 你 haven't there's no chance that 你 could be pregnant. Drinking 柠檬汽水, 柠檬水 and still being thirsty isn't a sign that you're pregnant...
Is this a joke? Unless 你 have had intercourse with a guy and he wasn't using protection 或者 he was and it didn't work 你 can't be pregnant...There needs to be 更多 facts 或者 signs give me 更多 details Like have 你 ever had sex?
