Hematite hi,
Here are a couple of good sources of information about cancer and fertility which include information relevant to your question.
A discussion on the Breastcancer.org website called "Fertility, Pregnancy, Adoption" - go to the following page and look in the left margin for _link_s to each topic covered
http://www.breastcancer.org/tips/fert_preg_adopt/One of the topics is called "Will Chemotherapy Make You Infertile?" - it's on this page
http://www.breastcancer.org/tips/fert_preg_adopt/fertility/chemotherapy.jspIt includes this comment "Early menopause brought on by chemotherapy may be temporary. In other words, your menstrual periods may stop and then start again after treatment is over. It can take a few months or as long as a year or more for your periods to return".
This FAQ page on the fertilehope.org website (scroll down the page for answers to each question listed)
http://www.fertilehope.org/learn-more/cancer-and-fertility-info/faqs-women.cfm#topI suggest browsing through the relevant information on those two websites and it will give you a better idea of whether you could still be fertile and what you may be able to do to find out if you are still fertile.
Cheers,
Ed.
