When Joy-Anna Duggar and Austin Forsyth got married back in May, fans of Joy's famous family were full of questions.
The biggest mystery surrounded the date of the nuptials.
For some reason, Joy and Austin moved their wedding from October to May, and never offered an explanation as to why.
Three months later, Joy-Anna announced her pregnancy, and everything started to make sense.
Fans reasoned that Joy and Austin had violated the famous Duggar courtship rules by engaging in premarital sex.
The rescheduled wedding was viewed as an attempt to conceal the fact that Joy had gotten pregnant before saying "I do."
The fact that Joy-Anna has all but disappeared from public view in recent weeks hasn't helped her family's efforts to convince Counting On viewers that she waited to have sex until after she was married.
Joy and Austin were both absent from this year's Duggar Thanksgiving photo, but it's possible that they simply decided to join Austin's family for the holiday.
Whatever the case, the effort to keep Joy out of the spotlight has done little to silence suspicious fans, many of whom have done some digging to unearth what they believe is solid evidence of Joy's premarital conception:
That's a photo from Joseph Duggar and Kendra Caldwell's wedding that took place back in September.
As many fans have pointed out, Joy would have been about four months pregnant at that point, but it looks as though she may be further along here.
"That bump is NOT 4 months," tweeted one viewer. "She's at least 6 months pregnant!"
Duggar defenders have repeatedly used the "every pregnancy is different" argument to explain what appear to be discrepancies in the timeline of Joy's pregnancy.
But the evidence that Joy isn't being entirely truthful does seem to keep piling up.
Some skeptics point to an October Instagram post in which Joy stated that she could already feel the baby kick.
Doctors say first-time mothers generally don't "until closer to 25 weeks."
Again, not exactly solid evidence that Joy got pregnant out of wedlock, but it's not hard to see why so many are suspicious.
Several medical professionals have stated that Joy-Anna is further along than she claims, but their opinions are based only on photos of the 20-year-old mom-to-be.
Whatever the case, you can be sure that if Joy and Austin did engage in premarital sex, the Duggars will continue to do their damnedest to cover it up.
