Who might have a bun in the oven on The Fosters?

That’s what concerned mamas Stef and Lena are wondering after they find a pregnancy test box in the trash in Monday’s episode (ABC Family, 8/7). Their suspicions immediately turn to their MIA daughter in TVLine’s exclusive video — but it’s not the one you think it is!

While Mariana is the one who recently lost her virginity — unbeknownst to her moms — Lena and Stef think the fact that Callie’s not answering her phone (and has even turned it off, gasp!) means she’s hiding something from them.
