Hi,
Welcome to ehealthforum,
The exact ovulation day can vary and the rhythm method can put her at risk for pregnancy, as it is difficult to predict her exact ovulation date. She can be at risk for pregnancy if you had been sexually active after she finished her periods as she will become closer to her ovulation time after finishing with periods. If she had been during her fertile days and if fertile mucus had been present at the time of intercourse, sperms can stay alive for 5-7 days and fertilize the egg upon ovulation. After ovulation, egg has only 24-48 hours to get fertilized. The pullout/withdrawal method is known to have highest failures, hence, chances of pregnancy resulting due to contact with pre-cum or semen cannot be ruled out completely (pre-cum/pre-ejaculatory fluid is known to contain sperms and no man can be 100% sure that pre-cum/pre-ejaculatory fluid did not leak out during vaginal penetration). If worried, she should have considered taking emergency contraceptive within 48 hours of intercourse to prevent pregnancy. Wait and watch for her periods. Look out for development of any new symptoms if pregnancy is suspected. She should visit her doctor/gynecologist for further evaluation and assistance if she does not get her periods within 10 days of expected period dates, or if she gets abnormal bleeding. If pregnancy gets ruled out and if you are not ready for pregnancy, but intend to remain sexually active, you should consider getting her started on suitable regular birth control measures to be protected (after her periods). She should be regular with birth control use as instructed. Avoid having unprotected sexual contact if you are not ready for pregnancy.
Take care.
