The first time I got pregnant, I got a BFP on 12 DPO...but unfortunately I miscarried. I am TTC again and tested today at 12 DPO and got a BFN. Is it possible to still be pregnant and not test positive today even though I was positive on this day last time? Also, I ovulated early this month so if I was to be pregnant, I would only be 3 weeks today which seems a little early....help please!
