Digital OPK tests say 2 different things 😭


I’ve had a flashing smiley for 6 days then ran out of sticks for that box. I open new box and it’s straight to blank! Have those flashing smileys been false? So I did both tests at once this morning and one gave me flashing (old box) one gave me blank again😭 which do I believe?! I hate this truly I do. We’ve been ttc for 4 months my periods suddenly disappeared and I’m not pregnant. I haven’t gotten a period since September.
