Missed period, negative pregnancy test

Rachael

My husband and I started TTC last month. I have been off of the pill for 3 months after being on it for nearly 7 years. My period has always been extremely regular and has only ever been late/early if I messed up my pill. I am now two days late! I took a Clear Blue digital test the first day of my missed period and it came back negative. Today I took a First Response manual test and again it came back negative. Has anyone ever been in a similar situation where you ended up being pregnant? Is it just too early to test?
