Clearblue digital vs First Response

Ok so I took a first response test on Tuesday and got what looked like a vvvf line. Being the anxious person I am I wanted to take another test today so I took a clearblue digital and it very clearly said Not Pregnant! :( so I just wanted to know others opinions. Is first response just more sensitive or is the digital accurate? Should I retest and when? Ugh this is driving me nuts! 😕
