Hey moms so quick question. I googled & saw that the 2nd line on the test is an evaporation line.... Iv tested with this brand for both my pregnancies with my son’s & never had an issue. Idk maybe it’s a bad batch. But im only 2 days late on my period. & I honestly havent been feeling like myself.... Iv been so tired lately all i wanna do is sleep , iv been emotional , , iv been craving like crazy , i just want to sleep & eat , iv also been getting heart burn...& It happens enough for me to question why it’s coming to frequent . LITERALLY I had a miscarriage about 2 months ago . When i found it , it was basically the same symptoms , i took a test & it came out negative. I ended taking another test about 3-4 days later & that one came out positive. Has this happened to any of yall when testing & it actually be a positive? & should i buy one of those 5 days sooner instead? Because usually when you’re pregnant it’ll come up , but that wasn’t the case with the Pregnancy i recently lost. Im re-testing in a couple days anyways......
