But how can it be?
Jill: Don't think so unless Tybalt put her underwear back without washing it and Jill didn't notice and wear it (don't want to think about it)
Maya & Josy: MC is Mayas first, Josy had no other boy/man for a longer time, so no opportunity to get impregnated.
Bella: No James, Steven tried to get to fuck her but (until now) she refused, no other known man who could do it.
Sage: Maybe Chad (but i don't think so), as we know there is no other man to do it.
So it could/would be an FI (Fuck Interest, one of the side girls).
