12 days late

Kir

My period is 12 days late I am going to take a test tomorrow. I waited this long because my period was 10 days late before and it came the next day. But since this time it’s 12 I am very concerned I do not want a child at this moment. My breast was sore the week I’m suppose to get my period and it is still sore. I did had a few cramping the week I’m suppose to have my period but it stop. My boyfriend and I did had sex for two days of the week my period was suppose to come. And yes it was unsafe sex. Am I pregnant
