Diagnosed with PCOS about 4 weeks ago now

I stopped having menses so I went to the doctor to find out why, well what I found out came as a huge shock and an eye opener. It made me realize that I still want children even though I have 3 kids. I have been doing a lot of researching in the past weeks and found out that it is mostly a hormonal thing with hereditary problems. My grandmother has tried to put her 2 cents into what is going on with me and I hate to admit she has made a little sense but I am not going to do what she advises... I don't take advice to well and the thought of going on birth control for 3 or 4 years when I am 31 and still want children kind of made me cry inside. My doctor is perfectly fine with my wanting more children and he has put me on a medication to help me ovulate. Because without ovulation pregnancy is out the window. My grandmother thinks I am on birth control. She still thinks that at this age she can control me. I have no support from my family in this way of thinking outside of my fiance. I am just so tired of being sick and tired. I am also pretty sure the m/c that I had before my middle child was my bodies fault now. After all I have been through with my childhood and growing up, I have this to deal with.
