So is it true TTC with a retroverted uterus is difficult?

Ok, so I just got a call from my Dr and he wants to see me in the morning. He was only going to call if something came back with my tests and he said the swab and pap both came back negative which is great. Which had me thinking wonder why he wants to see me then, so I opened the ultrasound report and it says - The uterus is bulky but the myometrial echo pattern is normal. The endometrium is thickened and heterogeneously echogenic either due to underlying haematoma or retained products of conception. I know I should just wait to see what my Dr has to say because it's probably nothing, but just wondering if anyone knew what on god's great earth this means? Does it mean I just have some sort of infection? I'm impatient I know....
