Mirena IUD Rundown – Pros & Cons of This Hormonal Birth Control

by Robyn

Before you take the plunge into IUD birth control, here are some pros and cons of the Mirena brand to help you get a better idea of what your body will go through.


LONG TERM – You get a 5-year stretch with this IUD. That’s 5 years of nearly no worry about pregnancy mishaps.

EFFECTIVE – No birth control is 100%, but the promise of 99+% is as high as you can get.

NOTHING TO REMEMBER – If you have the memory of a goldfish, and can’t rely on daily pills, you just have it inserted and forget about it.

FAST PREGNANCY – You can get pregnant after taking out your IUD, there’s no major downtime (you can get pregnant as soon as it comes out if you want).

LIGHTER PERIODS – If you are “blessed” with REALLY heavy periods, Mirena can lighten them up considerably.

REDUCED CRAMPS – Also, if you have bad cramps, there’s a chance this IUD will help with that too.

INSERTED STUFF – You can still use tampons and your menstrual cups if you want.

BREASTFEEDING – You can still breastfeed while on an IUD.

IT’S FAST – Insertion only takes a few minutes – with a total appointment of around 30 minutes.

PILL ALTERNATIVE – There are fewer side effects than the pill.

NO FEELING DURING SEX – Unless the string gets out of place (which can happen), you and your partner won’t feel anything during sex.

LESS HORMONES – If you don’t like the idea of large amounts of hormones in your body, this is for you.

“NO” SHUT DOWN – The official word is that it doesn’t stop your ovulation or hormone production – although those numbers are still under study and some say it can in the first year.


Even if the “chances are low” with some of the cons, it’s still important to know…

YOU’LL FEEL THE CHANGE – It’s not an “insert and go about your day” scenario. Your body has to go through some serious adjustments as it gets used to the IUD. This includes the first few hours where pain, dizziness, and bleeding might happen. If it goes on for more than 30 minutes, it might have been placed incorrectly.

CRAMPS – Your period might have fewer cramps, but you’ll probably have some really bad ones in the first month. And, out of all the side effects, it’s the most common.

LONGEST PERIOD EVER – There is a chance that some women might bleed or spot for a while – even as long as 3 months. If you are over 3-6 months, you need to get it taken out.

INFECTIONS – Mirena comes with a higher risk of yeast, pelvic, inflammatory, and other such infections. So, if you’re already prone to some of these, you’ll just end up with more.

CYSTS – 12% of women could have ovarian cysts develop. Normally, they go away on their own, but sometimes they can persist. If you have pain in your abdomen for more than a few hours, you’ll need to get to a doctor/hospital.

CLUMSY DOCTORS – Granted, the chances are REALLY low, but there have been a few cases where “perforation” happens. Aka, they’ve poked a hole in your body.

IT CAN MOVE – Some reported cases say that the device has either fallen out or moved out of place (and even embedded itself into the wall of the uterus). Also, if it moves, it might not protect you against pregnancy.

 PREGNANCY – If the minuscule chance of pregnancy WHILE on your IUD happens, it can be very dangerous for you, the baby, and fertility.

STIs – It doesn’t protect against sexually transmitted infections. If you’re going to play with someone whose status is unknown, you’ll still need to use a condom.

FEELING SHITTY – There’s a chance of nausea, mood swings, headaches, breast tenderness, and bloating. Fun.

DISCOMFORT – This isn’t advertised but many people say that if you haven’t had children before, an IUD might be more uncomfortable.

CONFLICTS – There are several conditions or medications that do not mix well with Mirena.

This is just SOME of the information surrounding IUDs. So, after this particular info-dump, if you want to give it a go, I would suggest further reading on what happens during the appointment, medical conflicts, and other important details – as well as contacting a healthcare professional.
