Pregnant or paranoid !!?

My boyfriend and I had sex 3 days ago and he came pretty deep inside of me (it was ALOT too)
I'm due for my period in about 4-7 days . I have cramps but they don't really feel like my normal pre period cramps . It's just like a pulling/pinching sensation. I'm pretty certain that I ovulated later than what glow said . And if I'm right I finished ovulating 5 days ago . I have no other period symptoms . Kinda hoping that I am pregnant this time 💕 opinions ladies ?
