I just got a call from someone who's been buying pregnancy strips from me for nearly 2 years, in packages of 10 (just once every few months). He called to tell me that his wife had gotten an early positive, waited another day & went to take a blood test. It was positive :-) He said that at first they were sure the test must be off (been there myself :-))... I'm so happy for them.
In other news, I read an interesting article about the use of IVF in HIV-discordant couples - particularly where the husband is HIV positive and the wife is HIV negative. Apparently, with the use of ICSI, they can guaranteed that the baby will not have AIDS.
