Last month I had my periods from 07th to 12th September, on the 20th we had sex and the condom burst, so 20th was suppose to start ovulating.. now this month I did not had my periods and was suppose to start on 4th October which means I am now 9 days late, the worst part is that on 3rd I had waist pain just as I use to be when starting my periods and until today I did not receive it, and I don't feel any signs of pregnancy on my body apart from swollen breasts as normal for ovulation but this time they did not go back to their normal size they are still swollen but not paining anymore. My question is it possible that I might be pregnant but not showing any signs if so when will I start showing them?
