My husband and I were TTC for the first time since last month. The first day of my last period was on Oct.26. I think I have a 30 day cycle. I took the test yesterday Nov 20th. I bought first response pregnacy test because it stated that it can determine 5 days before your missed period (67% accurate stated on the back label). Sadly, I got a negative response . Am I testing too early? I really can't wait.
