I went for Hajj last year, but made some mistakes while performing the Hajj upon arrival. My wudu was nullified during the tawaf and I did not go to redo it, rather I continued with tawaf not knowing that repeating wudu was necessary. As well, during the sa’y (between Safa and Marwah) I did not climb up on Safa, but stpooed at the green line. I got my periods during Hajj, therefore, I did the tawaf on the 6th day of my cycle when I was certain that it would end. However, I was surprised after the tawaf to see some discharge from my vagina.

What shall I do in this instance?

Should I take a bath and repeat the tawaf, keeping in mind that when I saw the discharge, I was still in ihram? Do I need to offer a sacrifice for any on the abovementioned?

Praise
be to Allah.

Firstly: 

The correct view is that being
in a state of wudoo’ (in tawaaf) is Sunnah and is not a condition of tawaaf
being valid. For more information, please see the answer to question no.

Secondly: 

In order for sa‘i to be valid,
it is not essential to climb as-Safa and al-Marwah; rather it is sufficient
to cover the distance between them, which nowadays is marked by the ends of
the pathway used for wheelchairs. 

Thirdly: 

If what you mean by the green
light is the place in which it is prescribed to run, then your sa‘i is not
valid, because you did not complete it. Allah, may He be exalted, says
(interpretation of the meaning): “Verily! As-Safa and Al-Marwah (two
mountains in Makkah) are of the Symbols of Allah. So it is not a sin on him
who perform Hajj or Umrah (pilgrimage) of the House (the Ka‘bah at Makkah)
to perform the going (Tawaf) between them (As-Safa and Al-Marwah)” [al-Baqarah
2:158]. Going between them is done by covering the distance between
them. 

Based on that, if a person does
sa‘i but does not reach the bottom of the two mountains, which nowadays is
marked by the ends of the pathway used for wheelchairs, then it is as if he
has not done sa‘i at all; he has to go back to Makkah and perform sa‘i,
because sa‘i is one of the pillars or essential parts of ‘umrah, without
which it is not complete. 

But if what you mean by the
green line is something other than what we have mentioned, then you have to
explain more clearly. 

This has to do with the ruling
on one who did not complete sa‘i between as-Safa and al-Marwah, and you
stated that this happened in ‘umrat al-qudoom (‘umrah before Hajj upon
arrival in Makkah); therefore what appears to be the case is that you were
doing Hajj tamattu‘ (where the pilgrim enters ihram for ‘umrah then exits
ihram until it is time to enter ihram for Hajj), and that this occurred
during ‘umrah. 

If that is the case, then you do
not have to do anything, and your ‘umrah and Hajj are valid, but the type of
Hajj turned into qiraan instead of tamattu‘, because you entered ihram for
Hajj before finishing the ‘umrah of tamattu‘.

no. 109267. 

Fourthly: 

If you were certain that you had
become pure following the end of your menses, then any discharge after that
does not matter, because of the words of Umm ‘Atiyyah (may Allah be pleased
with her): We used not to regard any yellowish or brownish discharge after
becoming pure as being of any significance.
