Hi doc, I need your advise I had protected sex with my partner on 6 oct with condom, and later we checked the used condom it won't got teared, and my periods date is 13 but it get delayed by a week and I got it on 21 oct but it last for only 2 days. I am having mild pain in lower left side abdominal. So I tested urine pregnancy test yesterday but it shows negative result. Do there is still any chance of pregnancy. Or risk of ectopic pregnancy?
