Pregnant.??

Ok so in January I got birth control Paraguard IUD because some guy had cum in me and I used it as emergency contraceptive and I ended up getting my period on February 5th and according to the app I should’ve gotten mine a couple of days ago but I haven’t.. I had sex for like 1 minute because something happened so we couldn’t finish and he did do it raw this was on February 14 and I had my period the week before. I feel nauseous and sometimes I get cramps. Before getting the iud I have never felt nauseous during my periods so idk what’s going on. I just want to get my period already 😭 is this normal.? I took a test yesterday and it came out negative.
