So frustrating!

40+5. I had my membrane sweep yesterday at 4pm. Woke up at around 2am to irregular contractions. Started timing at around 3:30. From 4:30-5:30 all the contractions were about a minute and there was less than 4 minutes between them. I called my midwife and of course, right after I called her, the time between contractions let up a little. Have yet to have actual consistent contractions since then. I've been having them all day but the timing between won't level out. Anyone else been through this in their labor? Did you go into labor soon after? My husband stayed home with me today thinking that we would be in the hospital by now.
