<s>[INST] I'm 40 weeks pregnant and about an hour ago I think I lost my mucus plug. It was about the size of a quarter,  no blood but looked yellow and green. Since then I've had cramping.g back pain and a couple of contractions.  Is this something I should worry about. [/INST] Hi dear,I reviewed your complaints,I suggest you to go to your gynecologist because all you are complaining off are sign of labour.Your doctor might will do your per vaginal examination to check your cervix dilations n effacement .so I suggest you to better hurry....then worry.My best wishes with you for having a lovely healthy baby.good luckRegardsDr.Harpreet kaur </s>
