AceShowbiz - Whitney Port has experienced another heartbreaking loss. The reality TV star has just revealed that she lost her baby, two weeks after opening up about her possible "unhealthy" pregnancy.

The former star of "The Hills" first shared an update on her pregnancy when uploading a new reaction video to "The Hills: New Beginnings" on YouTube. In the caption of the Wednesday, November 17 video, she and her husband Tim Rosenman admitted they are "pretty upset" after finding out on Tuesday that the pregnancy is no longer "viable."

"Tough video today. We found out yesterday that the pregnancy is not viable," the couple wrote. "We are pretty upset but have been through this before and will be ok. We did not know at the time of filming and still wanted to get this out to you guys today."

Whitney also shared the news on her Instagram Story. "I'm so sad to say this, and some of you may have watched on our latest YouTube episode, but we lost the baby," she. "We found out yesterday, I don't even really know what to say here. I recorded a full verbal diary of all my thoughts and emotions last night that I'll put out on my podcast next week."

"Sending all my love to those of you dealing with this right now," the 36-year-old added. Deciding to focus on the positive side, she divulged, "And I don't want to be insensitive by making light of it, but glass half full - I don't physically feel like complete s**t anymore."

Whitney first revealed she was pregnant earlier this month. In an emotional video she posted on social media on November 3, the mother of one said she was seven weeks along, "which is supposed to be obviously be really exciting and it has been, up until yesterday."

She then detailed how she and her husband Tim found out that the pregnancy could be "another unhealthy" one following a visit to her doctor. "He said that he was pessimistic about this pregnancy and that he told me to get blood drawn so I would, I will get blood results back today and see if numbers are going up or going down. He thinks they'll likely be going down and then he is having me come in for another ultrasound on Monday," she divulged.

Whitney previously had a chemical pregnancy, an early form of a miscarriage that occurs when a fertilized egg doesn't fully implant on the uterus, and two miscarriages in July 2019 and January 2020. She and Tim welcomed their first child, a son named Sonny Sanford Rosenman, on July 27, 2017.
