Pre-period discomfort 5 days after unprotected sex?

[OhJess]

Okay I'm having pre-period discomfort lower right abdomen area (aka same feeling right before i start period just not as strong or barely noticeable) 5 days after unprotected sex using the "pull-out" method, and let me add I ovulated that day according to my calendar. I'm assuming I'm not pregnant because he pulled out, but as soon as he pulled out it seemed he came too quickly. I'm really hoping he pulled out before he came... I'm 100% sure he pre came inside. But he didn't ejaculate before that (our first round) and we used a condom the 2nd time right after just in case he still had semen lingering... Anyway that is the back story... so yes he pulled out but i'm not sure if it was exactly on time, and yes it was on my ovulation day, my question to you is how soon can i have symptoms of conception. i have irregular periods, last period was October 20-26th and my ovulation calendar said "possible date of getting pregnant from November 6th-12" the 10th being the day i ovulate which is the day we used the pull out method. I should start my period November 24th. Please let me know. I hope the weird feeling is not conception. I am a mother of two already with the same guy but so not ready for baby #3 and it's been 4 years since i've been prego so i don't remember symptoms.
