Did I test too early?

So I’ve been having some major symptoms of pregnancy such as spotting, no period/missed period in July, sore boobs, nausea, headaches/dizziness, insomnia. There are 2 times last month where it’s very likely my husband and I conceived the 16th and the 19th. I tested today with clear blue pregnancy test and it showed not pregnant. I’m thinking if I am, we got pregnant on the 19th of July. So if that were the case, did I test too early?
