Muggsey - I really don't trust the dollar store brands. If you are going to test I have read that First Response and EPT are one of the best to do. They detect some of the lowest levels of pregnancy but it is still not a guarantee. So if you test tomorrow make sure you get a good test. Good luck tomorrow and Happy B-day.
Hil - I wouldn't pay too much of interest on the statistics. If we went by the statistics I would be PG because I have unexplained infertility. Most people get PG in the first 12 months of TTC. My DH keeps on asking about stats and I just kind of blow him off. I know if I looked I could find them but I really don't want to know what the stats are. It is hard enough to keep PMA without having to look at what are the odds that this worked.
Val - Sorry you feel down today. I have been the same way, it is so hard to keep up PMA all the time. Every twinge, cramp, or sore boob I keep on thinking it might be working, but then other things will happen and I think it didn't work. You had some great blasts transfered so you have a really good shot at being PG.
Brit - Good luck on you Beta tomorrow. Sending you lots of BFP vibes.
Amanda - If we go on stats you have a great chance of being PG. I know I have heard that most RE's say that usually a person will be PG within 3 cycles. Third time is a charm.
As for me, my cramps are gone today so that makes me a little happier but I still have really bad PMA. This is how my body usually reacts before AF. I am POAS tomorrow so hopefully I will get a BFP!!!
