I have a cycle between 24-30 days, today is cd31 so I thought I would do a pg test this morning. I brought a Tesco own brand test. Tested with my first morning urine, waited 3 minutes and BFN. So I picked it up and threw it in the bin. Have gone back half an hour later and now a second line has appeared!! What does this mean? It says on the packet do not read after 10minutes, why is this? Could it be that my urine is so diluted it has taken half an hour for the BFP to show? I drink a lot throughout the day and my urine is always very pale yellow or clear even in the morning. Any help you can give would be good. Also I am getting a slight pain on my left hand side just around below my belly button. Sorry for the long post!!
