During my pregnancy, I learned so many things about my body — many of which sounded pretty gross. My “mucus plug” and how I could lose it was definitely no exception. In addition to learning about gross things happening to my body, there was always a long laundry list of things to avoid while pregnant. Everything from food, to drinks, to even some types physical activity. So let’s combine the two, shall we? What are some things to avoid after losing your mucus plug? Not to be one of those people adding to your ever-lengthening list of things to avoid during pregnancy, but depending on when you lose it, it could be super important to know.
When I first heard the term mucus plug, I didn’t really understand what it was, and I imagined it to look kinda like a wine cork. I also just knew that I was supposed to lose it toward the end of my pregnancy. I asked Dr. Jamil Abdur-Rahman, an OB-GYN and medical travel blogger for TwinDoctorsTV, to explain a little better what a mucus plug actually is and what happens when you lose it. “In response to increasing progesterone levels during pregnancy, the cervix produces a large amount of a thick mucus that forms the mucus plug,” Abdur-Rahman explains to Romper in an email interview. “The mucus plug basically functions as a barrier of sorts protecting the sterile womb from the ‘outside.’ By blocking the cervix, the mucus plug prevents bacteria from entering into the uterus.”
This critical job is so important because Abdur-Rahman says if bacteria gets all up in your uterus, you could get an infection called chorioamnionitis. “Chorioamnionitis can be both life threatening for mom and baby. And even if chorioamnionitis does not threaten the life of mom and baby, it can cause pregnancy complications like preterm labor and premature rupture of membranes (i.e., the bag of water breaking too early)."
So when do you lose it, and what are you supposed to avoid after it comes out? Abdur-Rahman says you’ll typically still have one until you’re about 36 weeks, because at that point, your cervix is supposed to start shortening and dilating and it “expels” the plug. If you lose the plug “at term,” i.e., at around 36 weeks, there’s nothing to avoid. However, if you lose it earlier than expected, there are some things to look out for because it could be a sign of preterm labor. Abdur-Rahman suggests avoiding any activity that may help introduce bacteria into the uterus. So no sex, masturbation, placing an object in your vagina, or sitting in a pool or bath if you lose your plug earlier than 36 weeks. You’ll know when you’ve lost your plug because there’s typically a “bloody show” in your underwear or when you wipe, according to Baby Center. It can potentially be pretty gnarly looking — ranging from looking like pink snot to black tar — so be warned.
But it looks like if you lose your plug at 36 weeks or later, you’re good to go and there’s really nothing you have to avoid once it’s gone. Anytime before that though, you need to be extra careful about making sure you avoid anything that may have any chance of introducing bacteria into your uterus. So no sex, masturbation, or baths, I’m sorry to say. Just one more fun thing about pregnancy, am I right? But at least when it comes out, it typically means you’re almost there and that much closer to holding your baby in your arms. Just give your healthcare provider a call in case labor starts up too early.
