plzz let me know

Please if you have time can you tell me what's going on in this serial. I left it two years ago when kiran was changed and was modeling. Some guys were teasing her and abhi got upset. Simran had her baby, and abhi would come to her house to see his baby. Something like that. Now when I started watching I am so lost…
Where was Urmilla and isn't she astha. Plzzzzzzzzz let me know whats going on . my family and I watch this show but we are so confused…
