If I had to take a guess, the "pregnancy" tag could mean at least:
1. Risky sex (The chance of pregnancy)
2. Impregnation (Pretty similar to the one above, but still different enough)
3. Pregnant sex
All fall under the same tag, yet mean completely different things. Some clarification would indeed be good. For me, 1 and 2 are the things, while 3 is not something I myself like. But as they're all under the same tag, I have to consult reviews and forums before trying (which is a good thing, opinions are always important).
