Can scar tissue from a tummy tuck (10 years ago) affect the results of a transvaginal ultrasound?

Can scar tissue from a tummy tuck (10 years ago) affect the results of a trans vaginal ultrasound???

Will it miss a fetus of about 13-20 weeks old???
I read that the scar tissue can interfere with the sonic waves.
Is this true

Blood and urine tests are negative.

Age: 45
Female
Medications: Female ā€“ allergie and medium for stomach
General Information: I had a tt 10 years ago
I have been feeling movements in my lower abdomen,
My belly is a little bloated but if I am pregnant I can’t tell cause of the tt.

My periods are irregular
And the last one was very lite

If the scar tissue can affect it, how?
