Could I be prego?

Af was supposed to come 5 days ago on 01/03 now it's the 01/08 I haven't tested bc I'm scared. It's happened that I'm late and after I test I get my period. But this time I feel a little bit of pressure (can't really explain the feeling) on the left side of my abdomen. Not sure if that has anything to do with pregnancy though. I bought a test today but am scared. Is it too early to test? 😔
