Rossi, 41, and Smiley first revealed her pregnancy on The Doctors in December, which they achieved after a vasectomy reversal on Smiley’s part and multiple rounds of in vitro fertilization (IVF). It has been a long road to motherhood for the former Bravo personality and Smiley, who celebrated 10 years together this past February.

“We knew that we had to go through IVF in order to get pregnant,” Rossi previously told PEOPLE. “We went through a round of IVF and in that round we had 14 embryos that came out of that. We were so excited and just beyond ecstatic about the results.”

But about six hours before they were going to do the embryo transfer, the pair received a phone call from the doctor “saying that all of the embryos had arrested and basically died.”
