Late on my period

Hey everyone! Just need some opinions, I’m 5 days late on my period not experiencing any symptoms whatsoever, took a pregnancy test yesterday morning came back negative

Was sick last week with the cold n flu so not sure if that’s what delayed it but what do you reckon I should do next n how long to wait before going to a doctor ? 🙄 my belly also feels n looks bloated but not a constant feeling only when I eat or drink
