Question: What are the chances of being pregnant if?

My name is mike and I am 21 years old. What are the chances of being pregnant when you're on birth control and are still getting your period.

User avatar Your risk of pregnancy while on birth control depends on the method used and how diligent you are in using it properly. No method is 100% effective but when used perfectly (i.e. no missed pills, missed condoms, etc.) they are quite reliable.

Having periods is generally a good indicator that she is not pregnant. Some exceptions occur but usually if there is a period after pregnancy occurs it is a lighter than usual.

She is still getting her period, however she tells me that they are irregular. Does this mean there is a strong possibility that she is pregnant. (She's on birth control also.)

User avatar Not likely. Irregularity is not usually indicative of pregnancy. Absence of periods would be the thing to cause worry here.
