the leaking started less than an hour after I posted lol

I don't have a white dot, but I do believe I have a red blood blister on my left... its constantly sore but more so after a feed, a real sting... i'm starting to think hes not opening his mouth wide enough in his latch which is causing my nipples to graze against the roof of his mouth... the pictures of latching babies seem much wider. Got an appointment with the doctor to remove my stitches on thursday so will ask lots then including his tongue tie.
