I got the Mirena IUD on September 12th. After a week I got on it I started my cycle then my cycle stopped after 7 days. November 7th I was having strong cramps that felt like contractions ( I couldn’t breathe , talk , walk , felt like I was going to pass out. Lasted for 1 or 2 hours afterwards I felt sick ) Now I’ve been having pinkish / brown discharge since Saturday the 12th , I’m supposed to start my period the 18th , me and my baby daddy been having unprotected sex since I got it , I’ve been having all the pregnancy symptoms the same as pms symptoms , ( cramps , pain on one side , tender breast , nausea , fatigue and I constantly want to eat , back ache ) feels like I’m having the same discharge and symptoms I had before when I found I was pregnant last time with my daughter she is only 3 months , does this mean I’m pregnant again ? , is this normal ? Or just wait till my period comes to take a test ?.
