I got operated in July. They removed a dermoid cyst from my right ovary. Since then I got my first period after the surgery on the date I was supposed to get it. Afterwards I got the second period 28 days later! However since that period I got 2 periods within the span of 15-17 days. My periods are rather heavy. I have to Change my pad several times a day. There are a few blood clots as well but they are rather small and stringy. Is this normal? Anyone else experience these crazy and heavy periods after removing a cyst?
