Answer
(Fatwa: 1145/662/D=1432)
If you had properly performed your first Umrah during Hajj days i.e. after Shawwal, and performed hajj after returning from Madina, your tamattu was valid. For the second umrah that you did after returning from Madina, you will have to give a dam (slaughtering of an animal) due to missing one round.
Now let us know whether after performing the second umrah though incomplete, did you come out of ihram by doing qasr or halaq or not? And whether you had intercourse etc in the state of Ihram or after coming out of ihram?
