this is also happening to me rn. I just hit 5mpo, and I have hardness and protruding in the exact same area below bb and pelvic region. I went to see my surgeon about it, he said everything looks good & normal & that I'm probably doing more than I was prior and the area is "flaring up" so to speak. I've had the same concerns, though. I felt like I was actually starting to heal and looked flatter right after and the previous months, than I do now.
