IUI question

Hi all, my husband and I have been due to start Medicated IUI treatment with injections however my last two cycles I've been travelling during AF so haven't been able to be monitored and therefore unable to go ahead 😰 We are due to try again this cycle but of course it's looking like AF will be due anytime now and I'm due to be traveling on potentially days 3-5 of my cycle. Has anyone else had this issue and still been able to go ahead with their IUI? I've called my doctors to ask advice but am still waiting for a call back and going crazy in my head!
