She is on Loestrin FE, and has correctly taken it everyday for the last year. We were having sex, and I finished in her. Pulled it out to find the condom broke. She had her period 4 days later, and it lasted 3 or 4 days. We had sex again after it stopped, but the condom didn't break this time, and now 5 days later she feels like she is about to start again. What are the odds she is pregnant? She only has her period once every 2 or 3 months. Could this be her body just getting used the the pill? Or what could it be?
