HELP!!

Hello! So I'm slightly worried about this month's

period. I have the iud Kyleena in place currently

and this is the first time my period has come

late. The month before last my period came on

the 29th then last month it came on the 22nd

now I am 3 days late and it's been 30 days from

the 22nd so should I wait until the 29th? Is there

any possibility that I am pregnant since I have an

ind and it's really rare? I'm scared and idk if to

take a pregnancy test. Has anyone else gone
