Hello, My girlfriend is on Birth Control and takes it everyday. We had intercourse on January 8th but the condom broke. She decided to take Next choice a little before 24 hours. She began to get cramping, mood swings, fatigue, backaches etc. about two weeks later. She took a pergnancy test (first response) 3 weeks after the accident which was negative. She then began bleeding for 5 days (not sure if it was implantation). Shes taken 3 more pregnancy test, about 4 weeks after the accidents which were all negatve. It has been 5 weeks and she still has a backache and just recently got a cold. I was wondering, what are the chances of her being pregnant? Am I worrying for no reason?
Also, were the pregnancy tests taken too early? She has irregular periods so its based off of the days after the accident (20-32 days later)
