I know I have said this before but I am so baffled that I gotta repeat it

HOW THE FUCK IS VAIJU PREGNANT AGAIN?? It worked in Ghum because Vinayak was born thru Pakhi. But in this goddamn show, Vaiju gave birth to Vayu. They are trying to copy Ghum leap but it makes no goddamn sense. Every time I come across a promo for this show, I wanna bash my head against the wall. How, pray tell, is it possible for this woman, who just gave birth recently, hasn’t even been few days ffs, to be pregnant already?? Did she have sex right after giving birth?? Which wouldn’t make sense because she was mad at Rana about baby swapping and they weren’t talking. So how did she get pregnant?? I know I shouldn’t be taking this seriously, but it’s so frustrating that I can’t help but irritate myself even more with this fucked up science.
