Hello! I'm dealing with a situation that stresses me me out a lot. Period is 5 days late. I'd like to mention the fact that my period is around 25-26 days apart, never regular, sometimes even 24 or 27 days. I had my last period on the 29th of January and it lasted for 5 days, and it was 21 days apart from my last period. Between 6th-12th of February I had sex with my boyfriend who was visiting me. In the past few weeks I've been stressed and went through a hard time due to work, exams and different discussions. On top of that, I went down with a flu. I haven't taken a pregnancy test yet, I have no pregnancy or period symptoms. What can be the cause?
Thank you.
