As you near the end of your pregnancy, your cervix will begin to thin out and dilate. As it changes, you may lose your mucus plug and find a gooey deposit in your underwear or on the toilet tissue after wiping. It is not uncommon for this mucus to be mixed with brown, pink, or red streaks of blood from the changes occurring within your cervix. Some women may lose the plug at 36 weeks' gestation, while many others may not lose it until labor has begun. Sometimes moms-to-be may not even notice that they are losing their mucus plug because it happens gradually, over several weeks, and they've already grown accustomed to varying but increased amounts of the vaginal discharge that often accompanies a normal pregnancy. If you are earlier than 36 weeks' pregnant when you see blood-tinged mucus, or if you have any vaginal bleeding beyond the first trimester, you should call your practitioner.
