What do you think?

November 2nd-8th was my fertile window. I had unprotected sex with my boyfriend on the 2nd, and then the 6th which was my ovulation day. On the 12th, my odd symptoms started. I haven't stopped cramping like when I was ovulating. My boobs hurt and I get small waves of nausea here and there. And those all started on the 12th and hasn't subsided. My period is supposedly due tomorrow (Friday the 21st). Usually, I feel crampy the day before my period but I have felt cramps ever since I ovulated and I don't feel my usual symptoms like I'm getting my period. I'm going to wait until I miss my period (if I do) to take a pregnancy test. But I just wanted your input on what might be going on and if anyone has felt something similar and what the outcome was. Just to ease my mind a little. Thank you!
