Hi I Just Wanted To Ask You. I Had Unprotected

Hi i just wanted to ask you. I had unprotected sex two weeks ago. It was my second sex in life. My boyfriend didnt put his sperms inside of me but i rather took morning after pill 15 hours after sex. It's two weeks after that and i have still weird feeling in my stomach. Can it still be because of the pill? Thank you for letting me know
That pill was Levonelle 1500
