Early pregnancy symptoms

I came off BC the end of February. I have been having 23-24 day cycles. My husband and I aren’t quite ready to try to conceive yet (hopefully in a few months) and we use the pull out method. For the last 10 days or so I have been feeling super tired (I usually have low energy but this has been more than normal), and today I feel a little warm and lightheaded/dizzy (I never get dizzy!) could these potentially be early pregnancy signs? We had sex twice on May 31 and this app says I ovulated on June 5, but I went to the gynecologist on Tuesday for my yearly exam and she said with a shorter cycle, I would be ovulating on day 9 or 10 of my cycle, which would have been June 1 or 2. I’m due for my period on Sunday or Monday so maybe I should just wait and see if it comes before testing? I guess my question is if there are any symptoms this early if I am pregnant and what the chances are with the pull out method?
