1 month pp?

My baby turned a month today so I’m assuming that makes me 1 month pp, right? Anyway I’ve been having burning while peeing and feeling a lot of pain on my vagina every time I stand up from sitting down. I would describe the pain as if someone was standing on my vagina! I was also looking where my stitches were and it’s red, my scar looks as if my stitches were ripped off instead of healing how they should’ve, and my discharge kinda had a order to it...I went to my obgyn she tested me for a Uti it came back negative. I’m thinking my stitches are infected! It looks like I still have two stitches when they should be gone by now. Someone please help because I’m to the point where I don’t even wanna go pee because of the burning
