If one’s Wudu' is broken after performing Tawaf

Q 1: I offered Hajj this year, praise be to Allah. However, I made three rounds of Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and in the beginning of the fourth round I felt something dripping out of me. I thought it was blood but when I went to the toilet I found out it was water. Yet, I did not repeat the Wudu' (ablution) but I repeated the fourth round and completed the Tawaf and after that I performed Sa`y (going between Safa and Marwah during Hajj and `Umrah). What should I do now? Is my Hajj invalid? Do I have to slaughter a sheep or repeat the Tawaf? I would like you to note that I was ignorant of the ruling here and I did so unintentionally.

A 1: It is obligatory on you to return to Makkah to perform Tawaf-ul-Ifadah because your Tawaf was invalidated by the lack of purification. Also, you are required to perform Sa`y (going between Safa and Marwah during Hajj and `Umrah) if you were offering Tamattu` Hajj (`Umrah during the months of Hajj followed by Hajj in the same year with a break in between), or if you were offering Ifrad Hajj (performing Hajj only) or Qiran Hajj (combining Hajj and `Umrah without a break in between) and did not perform the Sa`y after Tawaf-ul-Qudum (circumambulation of the Ka`bah on arrival in Makkah). Then, you are obliged to perform Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah) if you are late in Makkah. Moreover, if you have had (Part No. 10; Page No. 246) sexual intercourse during this time, you are required to pay the Fidyah (ransom) which is slaughtering a sheep meeting the same conditions for Ud-hiyah (sacrificial animal offered by non-pilgrims) in Makkah and to distribute it among the poor people of Al-Haram.
