3 missed periods!!!

Leyley 👑

I’ve missed my period for the 100th day today, and I’ve taken two pregnancy tests.. one the first missed period-negative and then another one on the second month before my period that didn’t come-negative also. the longest I’ve went without a period was 2 months... Should I take another test or can someone tell me what is going on??? 😅😅😅😅😅
