Factors that break and don't break the fast

Woman Bleeding Whilst Fasting

Q: I had a period of 7 days. I was bleeding on my 7th day but bleeding stopped by sehri of the 8th day. I took ghusal and started fasting but during the day, I bled little bit. I performed wudhu, cleaned my private place, kept roza, and read namaaz. Please explain to me if my roza broke or not? Do I have to take a shower again?
