She experienced irregular vaginal bleeding and thought it was her period, so she did not do Tawaaf al-Wadaa’ (Farewell Tawaaf)
Question

                When she wanted to do Tawaaf al-Wadaa’, she found that she was bleeding, and she thought it was her period. After she had returned home, she realized that she was pregnant and that the bleeding was irregular bleeding. Does she have to do anything?
Praise be to Allah.We put this question to Shaykh Muhammad ibn 
          Saalih al-‘Uthaymeen, may Allaah preserve him, who answered as follows: 
          
She does not have to do anything. And Allaah knows best.
