I have really regular periods. My cycle is always (apart from when I had small babies) 28 days, I track it. This month I’m 10 days late and no sign of it!
I bought a pregnancy test today (a pricey one as it’s all there was in the Co-op) and it was negative. I would have been surprised if I was pregnant, to be honest.
What else could it be? 10 days late is so bizarre for me!
