I’ve been the same and I’m pretty sure it’s their bum!
I have the same hard lump at the top of my bump but baby has been head down for over a month now - midwife said that’s just their bum in my case so possibly the same for you!
It's been a bum since week 20 for me but I know what you mean about it feeling like a hard lump!
Hello, I’m in the exact same position. Baby has flipped at 35 weeks and now they’re saying I have 1 week to flip them back or an ecv 😫 head down for 10 weeks until now! I really hope it’s just their little bottom for you!
It may be their bum! I wondered this but at every bump measurement they’ve confirmed he’s head down and engaged, maybe check with midwife!
