Night Shift

So last week I started my job (11/17) which was a graveyard shift from 12 am - 8:30 am and I was supposed to get my period on (11/22) Sunday and usually i will get my period the day before or the day after Glows predicted day. I’ve heard that some women will not get their period in the first month or so of starting nights so I wanted to hear other opinions until I decide to take a test on Thanksgiving. I’ve taken two cheap tests from Walmart one on Sunday (11/22) and one on Friday (11/20) and both were negative.

Update: took a test on the 26th and it was still negative. If I don’t have my period by Christmas I’m taking another one
