Positives with smu only

↞ηιcσℓε♡↠ • 15 very long years of ttc! Not giving up though!!

Anyone have this? Idk if it's faulty tests or what's going on. The last few days I'll get a positive with smu, no matter how many I dip, they are positive but only on that brand. They are 10mui and the negatives are 25mui. I either get negatives or vfl with other urine samples. I know I'm probably not pregnant but if there has been anyone that's gone through this please let me know!!

Top 2 are the same brand
