Pregnancy Without penetration. Girl?

Me and my partner had a dry sex on 21 January. Just foreplay and rubbing genitals and I am on condom Though. Ejaculated on condom but never penetrated that day or Before. She is virgin and I am Also. But still She have not got her period. There is no signs though like nausea or vomiting. Yes some day before or week she had Acidity and diarrhoea from junk food. She took O2 tabs and pan Dsr and some other medications. But no Bleeding till now and no cramps or breast tenderness etc. She had late period before also its not new. Her last period was on 02 january and her period was tendes to late when we meet in any month but never ever had proper sex like penetration. My age is 23 plus and I am a Reg. Pharmacist as well she also pursuing. But Still in confusion What is happening. Yes I know without penetration pregnancy is not possible and other things like the ovulation time is also a matter. But is it Seriously possible to get pregnant this way for a virgin girl?
