Woman's I'itikaaf breaking due to haidh

Q: I made an intention for sunnah itekaaf in Ramadaan. Unfortunately I was only able to sit seven days due to haiz. (Mufti I had miscalculated my days.) I have sat 1 day in itekaaf as qazaa and my intention for the fast was for a Ramadaan qazaa fast. Is this correct or do I sit for 3 days in itekaaf? Is my fast correct? Mufti was I sinful in miscalculating my days? It grieves me greatly. Please advise.
