My girlfriend have 6 days period due now but still she hasn't have any symptoms of early pregnancy. She was telling me she had drips of urine one day after we had intercourse and lasted for 2 days. Her vagina was itchy though. I calculated , her previous period was on 16 December and we had intercourse on 18 and her menstruation stopped on 19 December. I did not ejaculated inside her but I wasn't wearing any condom either but I'm very sure I didn't precum or ejaculated inside her. Then she ovulated on 29th December and again we had protected sex on 11th of January and now she is 6 days due period. I need your consultation.
