Thanks so much for your input and the information. I always feel better the more I know about this whole process....I went into this thinking I knew something when in fact I was completely uneducated.
I am so happy to hear success stories like yours, you are so blessed to have your babies and I'm sure the egg donor feels happy for you as well. (As I will feel so happy if this all works out for my IM!)
Don't worry about the hpt, it was early to get a result. I was able to get a home test result of positive the day before the blood test, but in both cases I was pregnant with twins, so the hCG level would have been higher and that would explain why. I am pretty sure that no clinic does a blood test later than they have to, and blood tests are more sensitive than home tests. My clinic said that often women come in for their blood test convinced the pregnancy didn't take, because that morning they took a home test and it was negative, and lo and behold, they were pregnant.
I don't know why the doctor did not have you do a couple of days' bed rest, but it doesn't mean he is practicing bad medicine. Some probably don't think it is as important as others do. Women get pregnant all the time despite not staying in bed for two days after sex, so I wouldn't dwell on it much.
If you are pregnant, they will probably give you a count that goes like this. 4 day embryos plus 7 days equals 11 days since conception. Add 14 days, so your number can be calibrated to the medical way of discussing pregnancy, which is from the first day of your last period. (When every book on pregnancy and every test and measurement are all based on a count that begins with the first day of an average woman's last period as "Day 1," IVF patients have to be on the same calibration as everyone else.)
Good luck, it's nice to hear from a surrogate because I was the receiver of donor eggs, and always wondered if she felt a little weird about the whole thing.
I am not an expert to help you with your question but i wanted to refer you to a wonderful surrogacy website if you don't already know it,
