Can stress affect ovulation?

Chelsea

We just decided to actively start trying again after a break from years of trying. My cycle is VERY very regular to the hour. (Based on my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> every month) I just took an ovulation test and it is as negative as can be, when I should be at my peak/ovulating in 2 days. My grandma has been on hospice all week, and ultimately passed away this morning. Can stress affect ovulation or does it only affect periods? I’m sorry if this is a stupid question, I am quite distraught at how starkly negative the test was. I should have done an OPK sooner but this cycle has flown by with the grief of my grandmother. I’ll attach a photo of test. Thanks for any insight
