Heart shaped uterus

I have had two successful pregnancies. The last one was 13 years ago. My husband I are trying again and haven't been successful. So my dr did an ultrasound and told me I had a heart shaped uterus. I was never told this before with my past pregnancies and everything I've read has scared the crap out of me and has discouraged me even more. Is there anyone out there with a heart shaped uterus that's experienced or experiencing the same thing? Or that can offer some words of wisdom. Thanks!
