Please help! When to test??

So I was supposed to start on the 3rd, I had light pink spotting on the 2nd and then maybe one little dot of pink on the 3rd. I just thought my period was here and continued to wear a pantyliner but on the 3rd I just completely quit bleeding. I have test anxiety and hate taking pregnancy test in fear it will just be negative. I also have endometriosis and just had surgery in August. So far I’m technically 4 days late. I’m also cramping like I’m on my period but it feels different. We want a baby so bad but I’m literally terrified to test! Ladies should I test now or just wait?
