Ok i'm kind of new at this but here goes. I'm 18, just graduated and scared to death I might be pregnant. My period was due 2 days ago and it hasn't come yet. It doesn't always fall exactly at the same time becasue i'm underweight for my height but it usually stays around the same time. Almost a month ago my boyfriend and I had unprotected sex twice in a week ... During that week, starting with the day before and ending the night we had sex the 2nd time, I missed 4 of my birth control pills. I dont know if I really have symptoms or if its all in my head bc im worried but im moody as all hell and normally I never have mood swings and I feel like I need to sleep all the time. I was just curious if anyone had any idea what the likelihood of me being pregnant was- im planning on taking a test if my period doesnt come by this weekend but i'm putting it off because I havent mentioned this to my boyfriend yet. I don't want to tell him until i'm sure but at the same time I don't know if I should tell him I think I might be or just wait until I know for sure. I dont want to scare or worry him ...Like my subject says ... I'm lost
