Torn my stitches??

I’m 3 weeks pp. I haven’t had sex or even anything to do with sex. My legs have been sore so i went to stretch them to ease the pain. I laid on my back and let my legs fall to the side and then i went pee and there was blood in the toilet. I wiped my vagina and no blood so i looked on my camera and my stitches tore! I had a second degree tear. I called l&d and they said if i dont have excessive bleeding to not come in. Has anyone ever tore their stitches and what was the outcome???
