not to start this argument again but it's really clear that it's fantasy/cosplay to some extent
Given that she claims to have given birth 15 times - one of which was quints, more than one set of triples, and several twins, she's talking 25++ kids - which would easily put her in the top-10 (well documented) numbers of children a woman has ever had. Frankly, if she were real, there would be articles about her.
For example, look up Carole Horlock - who was in the news a moderate amount in late 2016/early 2017 when the preggoalways blog was started. Frankly I think i think it's pretty obvious that preggoalways was inspired by Carole's story, because her story mirrors too many of the details: two kids when she was young, then a gap, then prolific surrogacy.
Also, for someone who has a pregnancy fetish, it's super funny that she only developed a fascination with lactation after the 12th or 13th pregnancy! Yeah, that makes a ton of sense.
my personal theory is that she may have been pregnant for real two or maybe three times since the blog has been running, but everything beforehand is made up fantasy. Just someone who has a fetish/fantasies about being pregnant but didn't get to be until pretty late in life and is indulging in some fantasies about how their life could have been different.
