There are lots of success stories but most of them have moved onto another forum or stopped posting all together. You might try some of the pg forums or the mother/child forum. best of luck to you!!
I am days away from delivering our son. We also had IVF and a 3 day transfer.
I was incredibly lucky to get my very first bfp after my first ivf. Nothing else worked for us. I delivered a perfect baby girl a month ago. I had no blasts though. Our embryos were poor quality so I had a day 3 transfer.
My fingers are crossed for your bfp!
I just found out today I am pregnant and first time IUI - I have to take one day at a time because I lost one at 8 weeks last year but If I can do it anyone can so fingers crossed it happens to you too!! best of luck.
