I am 22 years old unmarried girl. I have been on irregular periods from jan 2015. Only when I take tablets I get my period that too not normal very little bleeding. I was supposed to get my periods on jan 29 but I didn't so I consulted a doc took tabs then I got my period on feb 12 which lasted only for 2 days with very little bleeding. I have done thyroid test too which came out to be normal. Later I didn't get my period in march again I took tab then I got in april. Its like only when I take medicine I am getting my period which lasts only for 2 days with very little bleeding. My stomach is bloated and I get period cramps but I don't get my periods. I never had irregular periods this is the first time. I went through net then it was showing symptoms of ovarian or other type of cancer. Is there any possibility or doubt that may be I have any type of cancer? please do reply I am really worried. Thank you in advance.
