No test can promise 100% on the first day after your missed period. Sometimes it just takes longer. It can take up to two weeks to produce a positive test. However, yes, 25 miu is decent. First response early result has a better sensitivity, it's the most accurate test out there. you can visit their website for a $2 off coupon. EPT and clear blue easy are pretty good too, and the dollar tree/dollar gen tests are decent. Try to stay away from store brands like from walgreens, cvs, and ESPECIALLY walmart (equate). The equate ones are notorious for giving false positives. I've had my husband pee on one and it be positive. LOL.
