Thanks, JMR. Sounds as if you know what you're talking about. According to Wikipedia, a home urine test can possibly detect pregnancy 12 to 15 days after fertilization:

Then her claim could be sincere. But it's still too early to say. I'll call her later today, tell her to wait and see if her period arrives.
A valid question might be why she'd bothered to do a test before waiting a bit for menstruation. She claims she had an inkling about it, and that her complexion has gone bad with pimples--a sign she says. Yes, it could well be a scam, but the fact is I cannot know for sure.
To answer the question why I have even bothered when there are so many other more virtuous ones out there, I can only say, for bad or for worse, this person is in my life right now and I care about her. Call me a sap. And yeah, if she is pregnant, I certainly had an appendage in it. Call me responsible too.
As some might remember, I live in Hong Kong, which is a short flight away from Cebu. I have a three day weekend in early April. I'll try to get down there and see to this business first hand.
