Confusion 😅

So I’m a tad bit concerned and I kinda just want to hear other peoples thoughts, but April I didn’t have a period technically bc it was 2 weeks late which ended up being my period for may. Now my period is 4-5 days late again and this has never really happened to me. Should I be concerned? Or should just wait to see what happens? In April I took at home tests and a urine test and a blood test ordered by my doctor and they all came back negative. Uuggghh 😂😅
