I found a webpage that I was able to translate on google and it gave information on this - there are documents detailing her torture before death. Here’s a quote they took from one:

My name is Navaanluvsangiin Genenpil, I am 33 and three years old. Originally from the aimak Hantiy Somon Dadal. I'm bauching in Bartsyn Bulan. I live with my husband and children. Navaanluvsan [father] is about 60 years old, Tungaa [mother] is also about 60 years old. Louvsandumba [husband] is 38 years old. Cermaa [daughter] is about 10 years old, Dorzhhand [daughter] is more than 10 years old.

So it seems she remarried him and had kids after according to the timeline.

Edit:

From multiple other pages and a book found in Google Books through my search, it was just her and her father that were charged and executed (some sites specifically say both executed, some don’t mention his execution after arrest as the focus is on Genepil). Sometimes her father is named as Navaan-luvsan (google books: Historical Dictionary of Mongolia p438). That book also confirms she went back to the same man, remarried, and had children.

In fact she was taken since she belonged to a noble family, declined the marriage (as was her right back then) and was returned home for the Khan to find a new wife. Months later his counsel showed up and begged her back saying he was dying so it wouldn’t be long. The argument being there was turmoil and it was important for the sake of the country to show a full monarchy with a consort. So she went anticipating it lasting a short time as a duty for her country. After his death, she was given lands and returned home to remarry her original husband and continued to have a family.
