Doesn't mean a thing

It's very, very common. I have it, have never had a problem conceiving whenever I've wanted to and my periods have always been painless.
I only found out when I had my first scan with my first pregnancy and it was quite early and they couldn't see properly because of it. This has been the only issue with it really - always have internal scans in early pregnancy because with my uterus sitting further towards my back it's harder for them to see. By the time I get to my 20 week scan it's fine.
Don't worry
