Membrane sweep

2 cm dilated during my 38+2 week check up yesterday bt the doctor sent me home cus I’ve got no active contractions. 😣 Baby’s head is s already engage and “dropping” though. He did a membrane sweep on me to trigger my labour naturally and I’m currently hvg little spotting and mild cramps every nw and then. Mommies who did membrane sweep before, jst wondering hw long did you went to labour aft the sweep? This is my 3rd baby btw.
