I didn't get my period for 3-4 months because a blockage caused my a minute cyst.
I took homeopathy medicines. The last 4 months I've changed locations to delhi where I live in a hostel(from bombay) obviously, weather and climate contribute to hormonal changes. But in December, towards the end I got my period. And it went on. Ever since I've been getting my period for 15 days and the 15 day cycle got over a few days back. But now, I am bleeding again. What is the problem? Is it because it didn't happen for the last 4 months ?

How were you diagnosed with a minute cyst? Where was said cyst? I am more concerned with the possible blood poising caused by a back up into your uterus. Have you gotten this all checked out by a doctor there. I know it will probably be expensive, but it will help a heck of a lot more then we can here. I am stumped to be honest.

You need to be properly diagnosis. Which may be blood tests, cat scan and physical exam. No one can do more than guess, online, which can be very dangerous
