Good luck with your sono mod! Hope it is good news for you.
I ended up getting +OPK on cd23 and then AF 7 days later. So that's fun. At least my cycle was 29 days instead of 34.
Trying vitex and b-vitamins this month and also temping so will see how it goes!
Caringo - sometimes around O time I get ewcm with a little blob of bright red in it - almost like when you sometimes get a bit of blood in a chicken egg actually. Was it like that?
