The replies in this post is precisely why we need better sex ed.

There's an astounding number of people who aren't aware about PCOS or IBS and think that the woman in the ad is actually stupid for taking a pregnancy test.

I have both, and my doctor had to give me an hGC test to rule out pregnancy because my abdomen was as bloated as the woman in the picture.

Neither of these conditions are rare, and either one can cause bloating and swelling, often chronically, to this degree.
