Membrane Sweep

So this morning I had a dr appointment and found out I’m 3cm dilated. The dr also told me I’m pretty thinned out and gave me the option to strip my membranes which I took him up on immediately lol ... anyone have this done? How soon did you go into labor? ... this is my 3rd pregnancy and I had my last makena shot 2 weeks ago. My first two were born early with my water just randomly breaking so this is all new to me (and is why I had to get the makena shot). I’m currently 38 weeks, 3 days.
