hypoechoic mass on trans vaginal u/s

[summer22]

I got my transvaginal and pelvic u/s back and will not be talkign to my doctor until she is back in 2 days. I'm concerned about the findings and wonder if I am worrying too much too soon. I'm 45, still get regular periods on time and have 2 grown children. My results say:
uterus is retroverted and measures 8.5x 5.4x 5.6 cm.  There is a focal mass along the lt side of the body of the uterus measuring 4.7 cm probably representing a fibroid.  The edometrial echo complex measures 2.2x1.8x1.2 cm.  There is a small cyst 9 mm on rt adnexa. In the lt adnexa is a 1 cm slightly hypoechoic mass to the ovary. This shows no vascular flow and could represent a complicated cyst.  A follow up in 6-8 weeks is suggested. No free fluid is seen in cul de sac.
My questions: what is vascular flow and what does that mean?  
is 6-8 weeks too long to wait for another test?
what is "slightly" hypoechoic mean?
is there any chance that the uterus mass is not a fibroid? I had a pap and it came back normal.
thank you in advance

HI,
  IM NOT A DOCTOR BUT I THINK THAT IF IT HAS NO BLOOD FLOW, THAT'S NOT A BAD SIGN BECAUSE TUMORS NEED BLOOD FLOW TO GROW.

in answer to your reponse and question... I really did not have any sx's. I went for a pap and pelvic exam, my gyn felt a fullness in my lt adnexal region and recommended an u/s.
This is the first fibroid I've ever had also. Will it go away on it's own, or does it take menopause for that to happen?
Also, does "no vascular flow" in a cyst mean that it could be more serious? My last pap was a year ago from my regular doctor and she did not feel anything then.  Thanks
