Yes glenny_c, mine was 5 day transfer and nothing was mentioned about possibility of twins?? Brunette I would love twins, we do want to go for a second after this one, so may use two of the frosties later on! I've been told my estimated due date is 13 April 2011, clinic said I would be about four and half weeks, though just did an online due date calculator and it says 5 weeks, 2 days. Not to sure about that one... The results of my second blood test were hcg levels of 6300 and prosg. at 99. I do have this aching pain in my right hip, I'm hoping it just my body changing to accommodate the little one!?! My first scan booked in for 26 August, so will just go with the flow till then.
