Drug test & menstrual 😑😑

Help !! My stupid menstrual came 1 week late and surprisingly also heavy. Smfh. I started Friday and normally it lasts 4-5 days. So the last day will be around Wednesday. But my problem is this Monday I have a urine drug test for a big company NEW job they require before I start working there!! They will not allow the test to be pushed further so my question are there any ways to lighten it, or shorten it in time.

I’m pretty sure there’s not but at this point I’m desperate 😑😑 there’s a slight chance they can still do the Test but if it fails I can’t have another day off from my current job to re do the test.
