Am I pregnant?

I had a baby in January. I got the iud at the end of February... it fell out around May 23rd and I bled the entire time I was on it. I started my period the 25th of May and haven’t had one since. I’ve been sexually active & haven’t got back on birth control yet. We usually just use the pull out method. My SO says he has a gut feeling I’m pregnant, but I just don’t feel like I am. I don’t want to buy a pregnancy test and get my hopes up that I’m not pregnant. Thoughts?
