Well my bloods from Thursday (cd19) were 39 which was higher than I expected. I reckon they halve every 3 days (by my maths). I hope to get a BFN by next weekend based on that theory (20ish by today, 10ish by Wednesday, 5ish by Saturday). I have some 10 miu tests and propose to test next Sunday.
On another note, have had a bucket load of EWCM today. Anyone else had this post mc? Can't understand why as clearly not ovulating due to damn hcg in my system!
