Emilie,
I was told as a teenager that I would never have kids. I then had 3 miscarriages. While they were terrible, I thought that well if I'm conceiving maybe I just need to figure out why I cant hold it.
I was also told at my last miscarriage that I would never have children, and on top of that, to never try because of my melanoma. It really almost broke my marriage. Sometimes these doctors are sick sick careless people.
Never give up hope! It is an emotional roller coaster, but its just a test of patience. I was married for 5 years before our first, and it wasn't until I just gave up and decided to just enjoy my life with my husband that we were pleasantly surprised by my pregnancy.
Of course, going to the Dr at that time was also stressful. Can you believe that I actually had one Dr. tell me in my 27th week that my baby will be born with cancer because of my history with melanoma? Unbelievable.
Keep your head up, and never lose hope. Enjoy your life, be healthy and active and it'll happen some day.
Hope that helped
