Me and my girlfriend just had physical touch and I just rubbed with my private parts with her private part. It has been around 4 months and she is getting proper periods with one or two days ups and down. But today suddenly she vomit once and feeling little giddy and 3 days before she got hives on her face. But from 4 months we dint even touched each other. And no intercourse from before itself it was just touch. Please help me with good solution. Is there any chance of pregnancy.
