Hi..i Had An Oral Sex With My Gf. During The

Hi..i had an oral sex with my gf. During the intense of sex,I had caressed my penis on the mouth of her vagina.. I already released my *** before it ..maybe precum coz I never reached climax..n during caressing there was no release of pre ***..it had already released earlier. It was the first day after her periods got over n she’s virgin..i never had intercourse
…the worry now is she’s experiencing pain below her breasts..a burning sensation..is it any symptom of pregnancy..is there any chance she can be pregnant? Should she consult a doc or take a pill? Pls help
