Unusual uterus?

I hadn't looked on the myhealth feature my hospital has in a while because I didn't expect any messages from my doctor. This morning I decided to see what the lab report from the HSG actually says, which was a MISTAKE. It says that there's an indication of an arcuate uterus. This means the uterus has a dip somewhere in it. The indentation of mine is at the top (fundal). The scary part is that several sites say that while it won't affect getting pregnant it can affect successfully carrying to term. There were a couple of forums where women had asked about the topic, and some women shared stories of having it and being fine, so at least there's that. One site said that 2/3 of women carry to term, but what about the other 1/3? Are they likely to miscarry early on or go into preterm birth later? Ugh. It's amazing that so many babies are born in spite of all the crap that could go wrong. Furthermore, why didn't the doctor call me to discuss this instead of just letting me read it? I emailed the nurse to ask if I should be concerned, so I'll try to avoid freaking out until I get her reply.
