Should I be concerned??

So my period was very weird this month. Day one and two were very light I changed my pad once on each day (there was barely anything there)

Days three and four I had spotting that stopped in morning and there was no bleeding throughout the day I even had sex and there was still no blood

Day five I had light spotting.

I usually have a medium flow from the beginning to end. Is this something I should speak to my doctor about?
