Need answers! Labor soon??

Okay, more labor questions - so sorry! So, 38 weeks today, and my doctor said I was almost 2cm dilated (but super stretchy down there), thinned out, baby super low, and "I'm in the best position I could be in," AND she stripped my membranes! Well, I think I just lost part of my mucus plug, and I made hubby have sex with me afterwards (for safe measures lol). So I guess the question is, how long after you lost your mucus plug did labor come on? I'm getting super anxious and excited!
