home insurance lapse

home insurance issue. my house was broken into between 11 to 27 ab. my problem is my insurance policy expired?
April 17. I did my property again to discover the break of up to 27. So how can a break at a date yet to be determined. which means that it did not occur before or after the expiration and all my stuff was taken. I have to file a claim for my property. So how would that be? work called and reported the rupture as soon as I got in 27.
Yes, the way it works, if you do not know the exact date it happened legally use the date of discovery – that would be 27 April. Sorry, no cover.
