2nd Pregnancy. . . Maybe?? 🤷🏽‍♀️

Whit

So I’ve had my Mirena in for a year (9/26/2016 when it was put it) and my LO turned 1 on 8/16. Well I was due for AF 9/25 and there’s been NOTHING! Now I wouldn’t be upset if I was expecting, but my fiancé would seeing as this would be his 3rd and plus we’re supposed to be getting married 5/19/2018 and if I’m pregnant I would be due around that time. I know Mirean can mess with your cycle but I’ve been regular after I stopped breastfeeding so I’m wondering if I should take a test or just wait a couple more days and see what happens. Any suggestions?? Anyone else become pregnant while on the Mirena?
