We had our first donor cycle this time. Our donor is 30 years, she made 14 eggs, we received 7 eggs, 5 fertilised and we transfered 4 embryos today. I am 36. The status of the embies at the time of transfer were (with grade 1 the best and grade 4 the worst):
2 x 10-cell, grade 1 embies

1 x 8-cell, grade 2 embie

1 x 3-cell, grade 2 embie

My questions are:
1.What would be a realistic success rate for a pregnancy?
2.What are our chances of having multiples?
3.What date is the earliest that I can test (HPT)
4.What can I do or what should I not do during the 2WW?
5.Can we have intercourse?
Thank you and greetings from sunny South Africa
