Confused with period. (Posted in period group but had no reply)

My period came a day late and very light compared to usual, normally the first 2-3 days are very heavy, I normally cramp a lot and get very bloated, I’ve hardly any bloating or cramps. I am a bit sick, kinda like I have the flu, could that alter my period so much?

I doubt that I’m pregnant because my husband had a vasectomy last year, although he didn’t go back for the results.

Can Beijing flu-like alter your period so much?
