I haven't been on these boards for a while but my story. I have a ds 4 years old pregnant naturally 1 month prior to starting ivf. Had been trying for 14 months.
Trying for #2 for 3 .5 years 3 IUI's 3 ivf with own eggs pdg everything fine but age factor (maybe). They always put between 3 and 5 back in.
Moved on to Donor eggs thinking it was just an age factor
donor produced 14 embryos
