Unprotected sex during ovulation.

Me and  me gf had intercourse but, I did not insert it I just went halfway in just to foreplay but suddenly she say it's ovulating days going on which started from 27 Oct and we had it on 30 oct even I didn't ejaculate in her like there was little pre ejaculation fluid(precum). We panicked and stopped it immediately.The next day(31oct)she took ipill for safe side, she had gone through headache after having that pill after some she felt nausea but she didn't vomit(late night).The next morning(1Nov) during day she felt okay but in afternoon she suffered alot of cramp pains ,vomiting ,breathing problems complaining about white discharge so on she had pain in her breast. Now it 4 Nov and she is still suffering severe pains so is this normal? Or are these symtoms of pregnancy? If yes then what should be the next step taken.
