I only needed half a stitch, I'm not sure how long they take to dissolve. I'm 3weeks and 3days PP, I was done bleeding 3 days ago I thought I just had brown left over blood coming out. But these couple days I've been bleeding a lot more. I'm not sure if I started my peirod or if I ripped a stitch? I'm calling my doctor tomorrow but I want to know how you knew your stitch ripped?
