How many of you are irregular? 😣

I swear being irregular is very scary because it is hard to detect wether we are actually late from pregnancy or just having a late period. Well I had a VERY late period, approximately 40 days... OMG I was so worried and confused.. that was the longest day ever I was trying to think like is there a possibility or is Mother Nature just being an a$$ ... well I took a test and it stated that I wasn't pregnant and the next day I came on 😑😂 .. I guess after the test, it helped me calm down so things got back on track ... have any of you experienced this?
