No period, negative test

Cassandra

I’ve been off the pill for 3 weeks now, and usually when I stop taking my pill or I’m even late taking it, I start my period later that day. I took a cheap pregnancy test this morning and it came up negative. My boyfriend and I have been actively trying since I stopped the pill, could I be pregnant but it just be too soon to tell? I know that you are most fertile when you stop taking they pill.
