I have had my mirena for 5 weeks. I got it when my daughter was 12 weeks old. In the 6 weeks between my all clear to have sex and mirena we had sex at least 3 times a week. Since mirena my sex drive has plummeted! My friends think it is bc I have a 4 month old and two other kiddos but o don't think that is the case! I couldn't even wait until my 6 week post baby check up to make love. I started researching to see if it was something that tends to get better with time but it is not looking that way!
