I have a mirena iud on for 20 month and the last 3 month i havent have my period, 3 weeks ago i did a pregnancy test and it was negative i need to know what do i have to do/

i also have a mirena iud,and also stopped having a period,it happens sometimes.

however in saying that,no contraception is 100 % effective.

if your worried and feel you might be pregnant i suggest you contact your doctor for a check up.

for how long i havent get a period

i dont understand what you mean.

when i first got the mirena inserted i bled for 6 months and then a trickle and then nothing for about 8 months before it fell out.

when i got the next one in i bled for 2 months and then a trickle,now nothing.

however i feel well and have no other problems.

but as i said,no contraception is 100% effective and women have become pregnant with the mirena in, my advice is to see your doctor.

no one on line can tell you if your pregnant or not.

ok thanks for your help
