Copper IUD removal

Hey ladies...

I recently had my copper iud removed after 4 years during my ovulation (which I had no idea I was) on the 17th of April, my long time boyfriend and I had intercourse on the 21st of April (was already out of my ovulation stage as my last ovulation day was the 19th) my boyfriend totally forgot I removed the iud and of course released his swimming pals inside of me, I have been freaking out everyday since wondering if I’m pregnant or not... I have taken a test and their all negative it’s only been one week since I’m suppose to start my period tomorrow, but there seems to be no sign of it, or maybe it’s just my mind playing with me...

I wanted to know if it were possible to get pregnant this fast as I’m searching for copper iud but there seems to be little to no post about it...

Please help!!! The wait is killing me!!!
