Membrane sweep to start labor?

well i had my 39 week apt. today, and i am dialated to a 2, and my midwife asked if i wanted my membranes to be swept, i said yes. so she did that for me (i am so ready for my labor to start) anyways i she told me when doing the membrane sweep it is meant get my labor started within 24 to 48 hours. my question is i have been having contractions today, i have not yet timed them. and i am dialated to a 2 and 25% effaced and my cervix is softening, and i have already lost my plug, do you think i will actually go into labor tonight???? please i will take any advice thanks
