My period is normal 4 days at average and is a medium flow the whole time tell the last day and it slows down and stops. These pictures are my previous cycle lengths and flows

This period has been weird started out like spotting the first day second day enough of a flow to use a tampon than last night it practically stopped I didn’t wear anything and nothing is even in my underwear. So I technically had a 2 day light flow far fetch from my other cycles! I haven’t been on birth control also for About 2 years now so that isn’t what’s causing the periods to be different. Could it be from using preseed for the first time this cycle and I drank some premama fertility drink as well I’m wondering if maybe this can make my period weird or if maybe it could be implantation idk 🤦🏼‍♀️ any thoughts ladies? Sorry for the long post!
