Sorry to be the bearer of bad news, but it is absolutely the endo sweetheart. I've had it since my first daughter was born (she's seven now), & I can have cycles ranging anywhere from as little as 19 days to as long as 67. My periods themselves are always at least 7 days, sometimes 10, & absolutely horrendous. You never know if you've conceived because "missed" periods don't exist, you always cycle when you least expect, & when you do start, you feel like you want to gnaw out your own uterus out every month. The only relief for it is being pregnant, because all the hormones that your body produces for the baby apparently soothes the scar tissue. But be warned: it is LIVING scar tissue. You need to keep track of it & have someone monitoring closely, because if it gets worse, it can spread to other parts of your body, such as be wrapped around your spine or entwined in your intestines. I know from personal experience . It can absolutely interfere with the ability to conceive also, & with the ability to carry a pregnancy to term. I'm so sorry you're dealing with all this. Just wanted to give you a heads up sweetie... best of luck & baby dust!

I had surgery for endometriosis which was severe (stage 4 at the time of surgery) back in January and my cycles have always been between 24-33 days long, with an average of 27-31 days. I ovulate very regularly too.

I've suffered with endo since I was 13 and have always have regular-ish af. I've heard bad things about the mirena. Birth control full stop is horrible on the hormones within the body especially the longer acting ones. I used to take the daily pill to help with my heavy af from the age of 13 until I was 18. Perfect cycles timed to the hour, I kid you not! Then I stupidly asked for the implant in my arm and had an af that lasted 3 months!! Needless to say I had it removed and it took 6-7 months for my cycles to become regular again. Endo affects 1/10 women and is a big cause of infertility in women, but the reasons for that vary, it physically can stop an egg from being released, moving down the tubes AND implanting properly. I wouldn't say it would make your cycles crazy long or short though, there will be other reasons for that, possibly hormonal reasons.
