### input:
In 2008-2009 I was diagnosed with Ewing s Sarcoma. I did a years worth of chemotherapy and 6 weeks straight of radiation. They moved my right ovary over so it won t get damaged from radiation. I ve been in a relationship for over 6 yrs now and me and my partner really want to conceive. I am getting a little doubtful. It is hard for me to find out exactly when, or if I do ovulate because I don t have normal periods (every month ) my period only comes when it wants to and out of nowhere. I finally had a period on my own last month which really surprised me and made me happy. It s February 20th today and I should have started my period by now but haven t yet. On another note, last night me and my partner were getting a little touchy last night and he even noticed that I had a thick clear discharge in my vagina. I know it normally happens before a period but I m not getting no cramps at all. Which I always do before I start. I ve never had this kind of discharge are all before and I have been sexually active since the day I ended my last period which was in January 27th. Does anyone have any guess or answers at all as to why I had this unusual discharge last night and if this is some kind of sign, could I possibly be pregnant or is my body finally functioning the way it s supposed to. Since I did have a period last month does that mean I can and do still ovulate

Hi, Thanks for writing in. It is possible that after getting treated for Ewing's sarcoma by chemotherapy and radiation therapy, you have had a sub fertility and this is due to hormonal imbalance. If your periods are not regular then please consult your gynecologist and follow treatment to regularize it. Ovulation occurs 14 days before periods in most women. However since your periods are irregular therefore it is not easy to predict ovulation in your case. There are home test kits available to monitor ovulation or do ultrasound follicle monitoring around the time of ovulation. When your periods are regular then you might use the ovulation kit to know exactly when you are most fertile and conceive. If there is persisting difficulty in monitoring ovulation then there is a chance of pregnancy by artificial reproductive techniques. Please do not worry.
