My midwife checked me yesterday and I was 2 centimeters dilated then last night I took the castor oil shake my midwife suggested as well as drops to get the process rolling even more. After all this, my husband and I had sex and I experienced contractions even more painful than the ones from the night before but, they were irregular. Then this morning I went to the bathroom and wiped and had a big glob of brown and green tinged discharge but, no blood. Could this be my mucus plug???!!
