Hi just wondering if anyone could advise... I've been using the clear blue ovulation tests every day for the last 9 days, they've all been the flashing smilies... finally this morning around 9.30 I got a solid smiley so we DTT then. I've just used an old test kit (as I can't use the new one for 48hrs now) to see if the smiley is still solid and I've got an empty circle just 10 hours later. I surely can't of ovulated since this morning already? I'm worried I've now missed my window. Could the older test kit be inaccurate as it's not used to my LH levels? Thanks
