I am 17 and going thru a pregnancy scare with my gf

She is really panicking while i'm not because I rememeber being very careful and using protection, She tells me she feels nauseaous,has discharge and her boobe hurt. We did when she was on ovulation but again everything done right.Her period schedule is yet to come and I have confidence everything will he alright but it creeps me a little too what if. I can only have answers after her period dissapears or something and then its time for solutions not wasting time feeling guilty. I really want to help her feel alright until we find out and even there I will be here because its my duty to find a way. She is 23 and I know it wouldnt be a problem finding a clinic, being discrete and working it out with each other money but she is scared of the pill abortion because of the risks. What can I do more in this situation to help?
