Don’t know what to do

So I’m 4 days late for my period. I took 2 pregnancy tests today and they both came out negative. Idk if I should wait a few more days to take another one in case I took them too soon. The last time I had unprotected sex was July 26-28th. My boyfriend thinks I’m paranoid because the past year nothing has happened. But lately I’ve been getting mood swings, crying easily, fatigue, and random cramps. Maybe I am over thinking but when should I worry or take another test? Any shared past experiences and advice would help a lot. Thank you 😭💕
