So I have mirena iud placed and very recently I've been having pregnancy symptoms. Morning sickness, sore breast, pelvic pain, and constantly either hungry or thirsty. This has been going on maybe 2 weeks now, but on and off. So some days I feel all of these symptoms other I may just feel one or 2. Could I have gotten pregnant? Also my cervix has been low soft and open for 3 days and before it was high and closed. I'm not sure what it means.
