Bbhope... I just found out today why IVFA didn't make me wait again this time. It's because I only used 1 lot of the sperm in the last wait, and you get three goes before having to go back to the top of the wait list, so even though I've changed donors it only counts as my second go out of three. Thought that is better explained - firs time waited 4 months, then used the DS three times. Back to wait again another four times, but only used the DS once. Changed donor, so two goes available.
