Hi!
Quick backstory: I'm sexually active and have had the Mirena IUD since the end of April 2018. So far, I love how low maintenance it is and how easy the string check is. To this point, I've had the IUD placement checked a couple of times and I can typically always feel the strings when I go looking for them. I have not had a period since after the first week of placement.
However, every time I have a symptom that mimics pregnancy I FREAK out. Whether it's a headache, my back aches a little, or my nipples feel a little sore, I get anxious and really wish I would have a monthly period to rule out pregnancy. (Is it normal to experience sore nipples on IUD? It's nothing major, but hurts a bit if directly touched).
I regularly take pregnancy tests but I'm scared they're not accurate. I guess my main question here is that if I can feel my IUD strings and nothing seems abnormal, then is it safe to assume my IUD is working and doing it's job to keep my body baby free?
