Have also posted this in TTC over 35 as I'm 37 ttc #2! This cycle I thought I would use my cbfm after giving it 6 months break, I never reset it & was asked to test with a stick from on cd 6 onwards. I got my first & second peak on cd 11 & 12 & had what I thought was early ov pains in my left side but no ewcm. Thought this was slightly strange as I normally ov around cd 14/15. Decided to still use opk's & they were coming out negative until yesterday/today (cd 14/15) when they were positive with strong ov pains in left side + back area + ewcm. Confused? Your not the only one! I had with OH on cd 10 & 12 & will be hoping to dtd tonight, although he's not well so it might not happen. Now I'm not sure if I've covered my bases? Has anyone else experienced this? How I can I be ov for nearly a week??
