U r right. Today is your D28. How many days are there per your cycle? Do you know your ovulation day. Someone said the result can be know 8-9 days upon fertilisation. However, I believe it varies from girl to girl.
I did a blood test on D27 but was found -ve. However, when I use the morning urine to test today, there is a light line + a dark line. So, now very confused. I will retest tomorrow. I used Lifetech USA to test this morning (special price at Manxxxgs now). I will use Menthoxxxxx tomorrow.
