Help.

My period is 7 days late now and I’m slightly worried I’m pregnant. Me and my boyfriend were pleasing eachother safely by he would finger me then if I was pleasing him I would touch his penis but then my vagina was out of bounds he couldn’t touch. And recently I’ve been getting worried my periods late 7 days and I don’t have any regular symptoms of a period like cramps or anything like that. And my boobs have been extremely sensitive. Please help me out. Thanks.
