Avoid pregnancy. What will happen now?

Hi just wanted to know if my girl and i had protected sex on 22nd and gave her i pill in interval of 29 hours of it and she have not got any side effect from that pill even after protected sex she has taken I pill so may i know we shouldn't be worried about any unwated  pregnancy right now as she is just having a normal pain in her back and abdomen is it the sign of that pills working ! Because After the intercourse as i know we were protected even the condom was fine i have just taken this precautions because i wasn't sure if the condom was leaked from its base or not because i found a sticky white substance at the base of  condom so i wasn't sure it was my pre cum or her  vaginal discharge on condom lower base because condom was not broken and also I haven't ejaculated in condom during the time of ejaculation i did that in washroom but have taken this measure as a safety so should we be worried about it and what will happen now ?
