Kyleena IUD

I’m getting a Kyleena IUD tomorrow morning (Thursday) and i’m planning on meeting up with my boyfriend on Saturday and i really wanna have sex with him, do y’all think i’ll be fine to do that by then? after three full days of having it? or will i still be bleeding/spotting by then (my periods are typically 5 days long and i really only get bad bleeding and cramps on the first day and tomorrow will be the fourth day of my period). i’m just scared i’m gonna have a six month long period where i’m just nonstop bleeding and i won’t be able to have sex. help?
