need opinions

i had nexplanon inserted in about the end of september 2024. i got it out end of march 2025. i was bleeding constantly through that time and about 4 days after getting it removed the bleeding stopped. after getting it removed i got my period may 24th 2025 til may 30th 2025. since then i haven’t gotten my period. my period app says that i am 16 days late. i’ve taken two pregnancy tests, early detection ones on the 10-13th day since my missed period, and they both said negative. has anyone been late after having nexplanon?? my periods before were always weird, missing periods for 1+ months etc. but my period was normal before getting nexplanon in. i’m just worried.
