Hello guys, I am just wondering if anyone has tried the CB ovulation tests the advanced ones with have three options. I tried these 3 days ago and got a low reading so we dtd for fun. The next day I got a flashing smiley so we dtd and I had been using the urine at 12pm each day. I read the instruction and it said to test in the morning so I did that today and got a solid smiley / peak and hopefully shall be doing the dtd later on. Is this normal? I tried to do the tesco test and the left window isn't bright enough to detect ovulation so could this be wrong? I was supposed to have my fertile week on the 11-16th but my last period was late by 2 weeks. Any advice or similar experiences would be greatly appreciated. Thanks!
