Has anyone gotten pregnant.....

Has anyone gotten pregnant having unprotected sex on a fertile day using pullout method? I feel like we used (pull out) effectively but I didnt realize I was on my ovulation day when it happened. My period has been wonky coming every 12-17 days from may to July-August but my last cycle was about 24 days. I am now on cycle day 28 and slightly crampy my apps show 2-3 days late. Not sure what anyone else's experience with this is. I don't feel like I am actually pregnant I just think I am reading into it all too much. P.S. I would be extremely excited if I were pregnant we just weren't trying this time.
