Worried.. 🤷🏻‍♀️😩

Ok sooo.. I got my Kyleena iud about 3 months ago, and the first month I was cramping and irritated all month but I figured it wasn’t a really big deal because I doctor said that could happen, then my period was pretty normal, only about a day late and then 2 days longer than normal. But not a big difference so no biggie. Then, last month my cramping started a week early, no bleeding, then my period was 13 days long. Light and heavy. It was weird. And I was super tired and my boobs were sore and I just couldn’t sleep enough. Now this month I’m 4 days late on my period and there are no signs that it’s coming anytime soon. And idk if I should be worried or not because last month it was so long. Also should mention that a couple days ago my bf and I were drinking and smoking green and I got soooo fucking sick. Like I thought I was going to die. Everything was fuzzy and I couldn’t see very well and every time my bf would touch me like at all I felt like puking again. It was terrible. I’ve also started having super weird dreams about having a baby, which is crazy because I’m so not ready for that kinda stress rn. And I don’t want to talk to my bf about it rn because we’ve had scares before and it just makes us so stressed and I don’t want to stress him out over my worries unless it’s something to actually worry about. Should also mention that since I got the kyleena we have had unprotected sex, but he does pull out every time, just cause he’s not completely comfortable with cumming inside me, which I understand. Any ideas on what I should do?
