I've been under quite a bit of stress lately. Boyfriend leaving after abuse and havent been taking my pill for about 2 months. We broke up last week and to be honest with everything thats gone on I cant remember the last time we had sex. I know we definately did last month but I got my period afterwards. We didn't use condoms or anything. I am now 5 days late. Could it be due to stress? If we didn't have sex this month and I got my period last month could I be pregnant?
