Normal?

Hi ladies!

So, I got my IUD about two weeks ago now, maybe three, and I was finally able to make the pain and everything go away which was great! And then, I had slight pain again, had sex one day and I have been bleeding for the past three days. My period isn’t due yet, though it’s irregular, and I know it’s normal to bleed either heavier or lighter or not at all with it, but I just wanted to know if I should be concerned because I don’t think it’s my period, or if the IUD is going to do that to my body (or im just early). I know no one is really a doctor here, but just a little bit of help is all I need to relax my mind 😭
