Injects #2 Fails, but not as I had thought

I just found out that my last AF wasn't really an AF, it was a miscarriage. For whatever strange reason, I took a pregnancy test at home this past weekend. It was positive. I didn't allow myself to get too happy since I had just had AF, and not a kind of AF, not a light AF, but a full blown, bloody mess. Thus, I was confused that the second line appeared. But, I went in to the office and got a quantitaive HCG which was 148, a definate positive. I didn't allow myself to get too happy, but they told me to take the progesterone supplements and come back in three days for a second test. Today, the number was 84. So, I had a pregnancy that implanted, but didn't stay, and I miscarried it (which was AF). Thus, I learned that I can create a baby, and let it implant, but hopefully next time if I take progesterone, maybe it will stick. It still was difficult news to hear, but hopefully it will work next time. I only have two more left. I'm trying not to cry, and trying to look at this as a good thing, since it shows me that at least this stuff is sort of working, and hey, if I can concieve a baby, maybe next time it will stick and stay for the whole 9 months. I'm trying really hard to be positive. So, tonight I'll have a nice big glass of wine (which I have been denying myself for the past three days) and take my cold medicine to get rid of all this snot that is in my sinuses, and pray for it to work next time.
