Hi. I'm 5 days late for my period and kind of stressed about it. My last period was July 24-28, and then me and my bf had sex A couple times until August 9th, which was the last time we had sex. Also went on a road trip August 5-6. Then August 12-17 I went to mexcio. Couple days later my school started which was stressful then hurricane Harvey hit my city and that made me very very stressed. I want to know if traveling and all this stress may have an effect on my late period? Also I have very irregular periods. Sometimes they are 35 days, sometimes 43 days. Today would be the 42nd day with no period and I'm worried.
