hi all

i have been TTC for 3 months and AF was due yesterday. i usually get it right on time, and was expecting it in the morning, i tested yesterday (not very reliable test, had thrown out the instructions) and got a BFN. woke up this morning expecting it again, and it didn't come, but tested (not with 1st morning urine) with a first response and got a BFN.

is there any possibility i could be UTD?
