Spotting with IUD

I got the Mirena IUD put in just over a month ago….I am 6 months pp. I am breastfeeding so have not had a period yet since having my baby. However, since getting the IUD I’m having regular spotting…some weeks it’s been worse than others but I’m spotting on and off pretty much 4-5 days out of the week. It’s frustrating cuz I never know when it will happen, and so I either have to wear a pad 24/7 or risk ruining underwear…I have looked at period underwear. And also it’s started to affect my sex life as I feel uncomfortable having sex when bleeding…so my question (thank you if you’re still here) has anyone else experienced frequent spotting after getting the IUD? If so, did your body eventually adjust and the bleeding lessened or stopped? If it is always going to be like this I am seriously considering removing it. TIA!
