We are trying for a baby

My husband and I have been trying for a baby for about 4-5 months now. I got off the implanon/nexplanon implant right before we started trying. My periods are mostly regular. After my last cycle in June I was 3 days late for my period but eventually got it. Well this time I’m 10 days late so I took a test yesterday but it came back negative. Is it too early to tell if I’m pregnant or does that mean I’m for sure not pregnant? Any input is greatly appreciated!

If you were pregnant it would show up by now. Get a blood test if you’re unsure
