Is it too early to test?

So I asked this earlier where I explained that on the 11th I had safe sex since we used a condom. We were switching positions and failing to continue when I look back and see that the condom is full and I back away. According to the app I was on low fertility and my period was supposed to start today the 14th. Sometimes the app does guess my period correctly but sometimes I’ll be either too early or too late. Everyone told me I should be fine but I’m still paranoid so I went to dollar tree and got a test and did it at 5:30 pm today and it said it’s negative(I’ll attach the pic here too) was i too early to test? Or should that be fine? Please no mean comments I just genuinely wanna be fine🥲
