I thought about this before. But the thing is when I'm stressed it comes even faster ( in 25 or 24 days.) Which happend in my last period, but this time I'm very calm!!!
your menstrual cycle can change from 28 days to 35 days or even more. my cycle is usually 28 days but for a couple of months due to stress from college and work it changed to 34- 35 days. your probably stressed out.
For me, I'm not married so I know it's not an issue of pregnancy. It's something else, but I don't know what it is!
I suggest you wait for another week, if the tests are still negative, you should console a doctor!
I am in the exact same boat this month. Normally 27-28 days, this month I'm on cd 34 and still nothing and all negative tests.
