pregnant or not ????

I suppose to have my period yesterday but I didn't so I took a pregnancy test it said not pregnant .... so am I or not.... Im never late but since I just got my iud out last month I don't know what to expect ...

I did had a 3 day period when I got iud out then 2 day period two weeks after ... should I wait another week and take the test ???? we are so ready to get pregnant ..

my doctor said that most woman get pregnant right after taking the iud out
