What do you all think? 3 days before ovulation

So my and my partner are TTC, we DTD yesterday morning before he travelled away for work. Yesterday was 3 days before ovulation. Is this a good enough chance to fall pregnant with it being just the once 3 days before ovulation? Has anyone ever fell pregnant from DTD 3 days before ovulation?

I done a digital Clearblue ovulation test today which shown high fertility (flashing smiley). Is this a good sign too?

I checked the stick after and the two blue lines on the test strip looked similar colour, I’m not sure if you can go off that though?

Any advice much appreciated!
