After today's episode thinking...

Arjun- There's no way he could have known that his/purvi one night together could have led to pregnancy. People try and get pregnant for so long and these guys do it once and boom she's pregnant. So no way arjun knew about the baby when he agreed/coerced into marrying ovi.

Purvi - we don't know when she found out. But she's definately silly to come back to Mumbai full knowing that she's carrying Arjun's kid. But the show needs to move forward so she had to go back to Mumbai.

Archana - maybe that's how they'll kill her character...when she finds out Purvi is carrying Arjun's kid...Cus in india it is considered bad if you get pregnant before marriage... especially considering how commingled this whole family is already... that's a whole month away so maybe not

Onir - if he doesn't know that Purvi is pregnant with another man's child it makes absolutely no sense he's a gynac for goodness sakes. This can't be the one and only report of how far along Purvi is! So he definately knows.
