Implantation or af

Af was due today. Anyway wiped last night little brownish only when wiped

Today again only when wiping it comes normally I would spot then wake up next day to heavier bleeding but this time it not it the same. Af normal is 4 days longs so I’m on day 2 should I wait see how it goes over the next 2 days and then test or what. My boobs feel little heavy feel like to sick
