Baby girl coming soon!

How long after your doctor stripping your membranes did it take for you to have your baby or just go into labor? I will be 38w2d when my doctor wants to strip my membranes. I’m at 1.5cm and my doctor was able to feel baby last week and says she was a lot lower this week. I’ve always had the date of July 16th in my head which my doctor knew nothing of and I’m just thinking maybe she will come when I thought she was. I have my appointment on Tuesday!
