So as I said in the title I'm 4 days late for AF and around 16 / 17 DPO. I tested again this morning and got another BFN. The thing is that I have no AF symptoms (which usually are so bad that I would be glued to the sofa in a fetal position by now). In fact I have no symptoms at all apart from a really annoying need to pee all the time.

I am never usually late for AF, like EVER. I can usually set my calender and clock by my periods.

Has anyone else been in a similar situation and got a BFP later than the norm?

I'm starting to think that I'm going mad! Xx
