When to temp... 3rd shift?


So....... this may be a bit confusing but please try and stay with me πŸ˜„ I work a 3rd shift job 4 nights a week (12am-5am). I get home and go straight to sleep and get up when my toddler does around 10-11am. On the nights I don’t work, I try to sleep like a normal person but I end up waking around 7-8. All that being said, I have no idea when to temp! My period is extremely irregular, which I think is from my weird sleep schedule, because before this job I was suuuuper regular. So, I REALLY need to temp. Any ideas? Thanks so much!!!!
