Clear blue digital advanced questions

Few questions regarding clear blue digital advanced ovulation tests as i got my first flashing smiley face this morning. No.1- i noticed when i ejected the test that the line was very faint compared to a normal ovulation test peak. Is this normal? Do the tests not go by the lines? And no. 2- how long does it usually take to get a peak? Do you always get a peak? And No. 3- would it severely hurt chances if we DIDN'T bd today but did tomorrow?(im sick so really not in the mood)
