Hmmmm, had a very interesting 24 hours. I don't have a regular cycle so AF can arrive any time from 27 days to 32 days. Yesterday was Day 29 so I wasn't really surprised when I had a show of blood last night. I thought it was all over again for this month but today the flow didn't really get any heavier. Just a bit of spotting but lots of AF cramps, particularly in my back. And so I decided to test when I got home and there is a very, very faint second line (but definite enough for DH to confirm he can see it too). I suspect that this is a chemical pregnancy and AF will be slow to start but definitely arrive. In the meantime, I may be pregnant for the 6th time (that really blows my mind!)
