Hi all, I'm new to the group! My partner and I are ttc our first and after years of no success with frozen donors have switched to a known donor. It worked in May...and ended in m/c at 5.5 weeks. He lives about 400 miles away and since m/c my cycle has been less predictable. We have switched to using Baby Dust TYB in the meantime; does anyone else have any experience with this? Are there any reliable statistics available showing how long swimmers remain viable in TYB? Would love to hear about anyone else's experience getting knocked up through the mail!
