If she is really pregnant and she does not know it might be 1.5 months which means Raghu is the father of her baby. It might be shown as a flashback how he used her after their hot hot salsa dance, else there was no need to show that.
I have a feeling that both hers and ichha pregnancy are 1.5 months apart and they will deliver together, only nani and tappu know that tappu's baby is not veers, so they will swap it with ichas .
And then more drag of a serial. Uttaran will finish for me if this fake preg is not exposed or real preg is shown as a liability for veer ichha.
