Anytime you have unprotected intercourse, there is the risk of pregnancy. That being said, when used correctly & consistently, condoms are very effective at preventing pregnancy.
If your menstrual cycle is normally irregular, know when you ovulate can be difficult. If you bleed at irregular intervals, then you most likely ovulate at irregular intervals. Yes, stress, illness, change in diet, sleep patterns can all affect your timing. If your period is more than one week late, do a pregnancy test. If it is negative, wait another week. If your period still has not occurred, repeat the pregnancy test.
You may want to consider beginning the birth control pills, not only for the birth control, but also for the cycle control. Being on the pill would regulate your body’s hormones so you would have regular monthly periods.
