I just want a little of help. I come on my cycle everymonth on 27th. I would like to know what is my menstrual cycle length? When will I ovulate and if possible when will the egg be released?

It sounds like your cycle is about a month long, so roughly 30 days (we can't be exact because if it always starts on the 27th, it varies). Calendar months range from 28 to 31 days, of course.

As for when you ovulate, you would have to learn how to read basal temps, mucus and other indicators, of buy a kit for determining this which is available from most pharmacies. It's generally the middle of the cycle, but there is variation.

No, it is almost impossible for your cycle to start on 27 every month, that means some months it is 28 days, and other months it is 31 days, and it works exactly like the calender.

So sorry but what you say just is not a normal possiblitity,

Next still would not know your ovulation date, since all people do not follow a day chart based on period, you will have to tract it , though testing, such as body temp and find out when you really ovulate.
