A quick hours question

For some reason my brain isn’t working today.
Having had the weekend off 24th-25th March
I Worked Monday 26th through to sat 31st
Rest day Sunday 1st April
Then worked this week Monday 2nd up to weds 4th
Today 5th I’m off (by choice)
Am I right in thinking that I’m safe to work Friday and take sat/Sun off, or (doubtfully) can I work fri/sat and take sun/mon off before working tues?

Yes, you can work Fri 6/4, have 45 hrs weekly rest, then work Mon 9/4. And yes also, you can work Fri 6/4 AND Sat 7/4, have 45 hrs weekly rest, then work Tue 10/4.
