Bump pain

36 weeks tomorrow and I feel like my bump hurts all the time. Especially if I move from one position to another, like standing from lying down. Went for a 20 minute walk earlier and it was hurting the whole time. Like a dull ache across the middle of my stomach/around my belly button. I don’t think it’s contractions as the pain doesn’t come and go, it’s more or less constant. Anyone experiencing anything similar? I’m not looking forward to the next 4 weeks!
