Pregnancy symptoms after Mirena?

Hi All,

So I got my Mirena removed 3 weeks ago (12/21) and I only had one day of light bleeding but no real period yet the day after removal, but now I am experiencing pregnancy symptoms even though the few pregnancy tests I have taken show negative. My husband and I have had unprotected sex multiple times since getting it out thinking we could get pregnant, figuring it will probably take a while, but starting Monday (1/8) I have felt nauseous off and on, soreness in my back, bloating, lots of burping, urinating frequently, odd feelings down there when I run, itchiness (had this as a symptom with my daughter), some insomnia and a strong sense of smell. I’ve heard of the mirena crash but I haven’t had anxiety or mood swings or any bleeding beyond the one day. Did anyone else have a similar experience/symptoms after Mirena?
