R called last night - it was nice to talk to her. Poor girl is so disappointed to keep getting negative tests. I did a little "research" on the internet before she called, and the basics of the information that I found say that pregnancy can be confirmed via blood test as early as 11 days after conception and by urine test as early as 13-14 days after conception. Well, at best, we're 11 days today - and I really think that we'd be a little behind that anyway, but maybe not... "conception" (fertilization) did occur 11 days ago, but implantation may have been delayed a day or two because of the transfer. Whether that makes a difference or not, I don't know. But, as I said - AT BEST, we're 11 days today. If she were TTC for herself, she would be waiting until the day before she was due to start, or the day she was due, before she tested - and that would be Sunday or Monday. I told her that it would be ok to get a quantitative assessment - if it's negative, we're going to have to face it sooner or later, right? Delaying it won't make it not so. She said that she'll go on Saturday if the lab is open; otherwise she'll go on Monday. We leave for the field on Monday - so I may not be able to find out until Thursday night. On the one hand, if I have to deal with the reality of a negative, it might be nice to get the news when I don't have the time to dwell on it. On the other hand, there are warrior tasks that I have to accomplish and be tested on, so bad news may be a distraction. Damned if you do, damned if you don't.
