I have a hormonal IUD for over a year no issues . My periods are so irregular. 15 days ago I had sex and they didn’t pull out .. I started spotting super light Monday and every day it’s gotten more and I have this today. I’ve taken pregnancy test everyday since and they have all been negative but I know it could possibly be to early still.. I’ve been cramping and headaches and sore boobs. Could this just be my period or could I be pregnant ?
