No. On the day my period was due I used my first urine to test got a BFN .. I was sure I was pregnant so at 2 that same day I retested and got my BFP. Turned out the reason my first test was negative is I ovulated later (2 whole days later) then I'd thought. Good luck.
Depends on the hcg level and how far along you think you may be.
If you have passed your af date, I tested positive on HPT. If you are in the early stages, you may be better waiting till your first morning urine sample.
Good luck, and wishing you sticky baby dust xx
