I feel like my body is tricking me 😒

Alright, I'm 38+5 with my first (a boy) and I've tried really hard not to complain or anything. But this is ridiculous. I just had another appointment and I'm still only dilated a fingertip. Three weeks of contractions off and on and three weeks of only being a fingertip. Dr also told me today that his head is still pretty high. This is so frustrating. Is anyone else this far and not dilated at all, much less dropped? We had a scan back at 34+5 and they said it looked like he weighed about 6lbs. I'm scared that he's just going to be huge and not be able to get down. I'm ik with him not being here yet, but geez body! Make me go through all these pains and then to not even make any progress is killing me. 😠
