Ultrasound/Sonograph after 30 day fast.

Hello all, Pardon to brother the community with the perils of my fast once again - but I really want to get the best info so I can perfect this fast as much as I possibly can.
I am 6 days away from completing my 30 day Water Fast in a series of other smaller fasts to shrink and remove a polycystic ovaries and larger ovarian cyst.

I am wanting to check the result of my fast by way of ultrasound/sonograph and am making arrangements.
Should I check this immediately as soon as I re-feed as in the next day, or should I re-feed for a month?

In one way I want to see the results directly after the fast before I get into the refeeding, however on the other hand I am cautious of what the medical staff will say about my scary appearance (I look like I have chronic anorexia) Will they try to hold me hostage and admit me or something?

Is there any quick and fast rules to this? My partner wants me to book the appointment the day after I break my fast to get the most accurate picture of what my fast actually achieved.... Re-feeding might hamper the picture - but I really want to hear the best way from others out there who have done this kind of thing.

Please note I have planned my re-feeding very strategically and slowly over 4 weeks on almost entirely plants... (I don't ever eat processed)

Can any of the fasting veterans give me the heads up of what they did to see the effectiveness of their fasts?

My GP already thinks my alternative methods are extreme but she is quite polite about it.

Pardon me for asking the forums for every little thing... I just really want to make sure my 30 days was not in vein and that I did all the protocols correctly.

Many blessing to all

PH
