Clear blue digital ovulation

Carly • I am 32 and from Southampton in UK. Me and my oh are TTC baby number one. Had miscarriage in January 2015.
Hi all. Has anyone experienced the following or have any opinions please as I am not sure what's going on. According to glow I am in my fertile week. I was taking clear blue dual digital at the beginning of the fertile window which I got a flashy smiley on Tuesday. I ran out of those and got some original clear blue digital (which don't give flash, just no or smiley) and started taking them from Wednesday and have had big fat O since. Could it be I didn't ovulate? I had ewcm Wednesday and yesterday and so we have dtd all week since Tuesday. Has anyone had this? How reliable are these digitals? Any advice would be soo appreciated. Thank you.
