Can anyone help re travel insurance?

[Mirage]

I'
m not quite sure what to do.We are going to Rhodes at the end of May & I am in the process of sorting out insurance.However,the quote I want to accept says that you cannot accept if you are undergoing or waiting the result of medical investigations.

I had to go to the Drs on Friday,because I've had stomach pains for over 2 weeks.The Dr was unsure of the cause but has asked me to send off a urine sample,to check for an infection.If that comes back clear,I will have to have a pelvic examination to see if it is anything else.

I don't know what to do about the insurance.Do I take out the policy & let them know if it turns out to be more than a UTI? Do I just not say anything & hope for the best?
I'm just confused & worried now.Can anyone help?
Thanks

If you're not going until the end of May, do you need to take out the insurance now? Can you wait until you know the results and then sort out the insurance?

I'm just worried,that with 5 of us going,if something happens to any of the others,not just me,we'll lose our money if we aren't insured.I think I'll just hang on & see what the test results say.
Thanks for answering
