My girlfriend had her last period on 15th September. We didn t have sex but there was a bit of precum around her anus. She missed her periods this month which were supposed to come on 15th of October. She had a yellow discharge and felt as if she was on her periods but there was no bleeding. She also noticed a very tiny clot of blood in her cervix mucus once. We did two HPT but both were negative. We got a bHCG test done on 23rd October and it came out to be 1.4, which is considered negative for pregnancy. We had sex 30th October but the condom broke. There was little to no precum and no ejaculation. We noticed it right away and pulled out the penis asap. She peed immediately and washed her vagina with soap. She took an iPill within half an hour of the intercourse. What are the chances of pregnancy and what can be done?
