Chances of Mirena IUD coming out...on its own???

Has anyone’s Mirena came out on its own? I’m kinda freaking out! So yesterday I went to my horse riding lessons... and boy was it bumpy, lol. I’m training on barrel racing horses. Anyways, when I showered I decided to check my strings and I have NEVER felt them hanging so low. I’m wondering if it didn’t come out of place. I’m not due for my cycle till another 1-2 weeks but I started spotting and cramping. It’s so weird. My doctors office doesn’t open until Monday. I know my fiancé will try to get lucky but I’m afraid it may hurt me if it’s out of place. My Mirena expires this December... so I’ve been thinking about having it removed. Then again, I’m not sure if I’m ready for baby #5. This would be mine and my fiancé first baby together. He REALLY wants a baby with me.. but it’s not that simple. Here’s why.. just a few reasons at least..

🚨We don’t have insurance.. yet.

🚨I have to get a cerclage..

🚨I have kids ages 4,9,13,16..

🚨I have anxiety

🚨I’m 33, fiancé 40

🚨I’ve lost a baby at 18.5 weeks

🚨We both have health issues

🚨We are trying to buy our 1st home

🚨Babies are EXPENSIVE!

But, I know he wants a baby of our own.. and I don’t want to regret not having one. 😔 Some days I get baby fever.. other days I think it’s best to raise the kids we have now and be done. Don’t know why I’m having such a hard time making a decision.
