Membrane sweep

How are all you people out here getting your membranes swept with little to no dilation? I’m barely dilated at a cm and my doctor said she can’t do the sweep unless I’m more dilated, yet I’m reading on all these people getting one without like any dilation? Ugh!!! And also about how you’re getting induced and 39 weeks instead of like 41 or 42! What! My doctor said if I don’t go into labor on my own they induce at 41. 🙄😭
