QUESTION..??.....Spotting 4days after period !!!!

Ja

I currently have been taking Metformin for about 3wks now..

My period lasted July 5- July 8 , I went to use the rest room today (July 12 am) && noticed a lil light bleeding..

First time that ever has happened.

Is pregnancy possible ? Any help would be great !! Been TTC 😇 for 4yrs ..
