Got a BFP this morning.......BFN an hour ago?

thats why they tell you to test with your first morning urine...you have the highest amount of hcg in your system. as you drink fluids througout the day and your urine is more dilute it might not have the same amount as early in the morning when you first wake up. so i would test again in the morning with your first morning urine with the same test and see what it says. if you are spotting and have had a positive home pregnancy test then most doctors will see you and do a ultrasound to see what is going on. mine did. good luck!!
