I've enjoyed reading the stories here and I'll share my own.
With DS8, we were going through infertility treatment and our first IVF cycle. We knew there were 4 embryos they had implanted. The morning I went for my blood draw, I gagged on my toothbrush and that made me a bit suspicious. That evening, when the Dr office called, they asked for me to stay on one line and DH to get on the other phone. The nurse told us the results were positive. DH was almost as excited as I was -- he gave me two carnations that day -- 1 blue and 1 pink which he bought on the way home. That's always been his optomistic attitude.
With DS3, I couldn't wait. We also went through infertility and an IVF cycle. I just couldn't wait the number of days -- what was it maybe 10 after they implanted the embryos?? The Dr did not expect me to get pregnant because things had not gone well. Anyway, I couldn't wait and I started buying home pregnancy tests and doing them about 5 days after implantation. I just kept testing every day hoping to get a positive result. By the time the doctors office did a blood draw, DH and I knew I was pregnant by all of the tester thingies laying around the bathroom....I didn't want to throw them out because "what if they are wrong".
