i'm 20 and me and my boyfriend regularly (3-4 times/week) have sex. i'm on yaz birth control and he pulls out most of the time. i got my last period june 12-15, but for about the past week or so i've been worried about being pregnant. i usually am though but i always get my period. i haven't really been feeling more tired than usual, although i've been a little hungrier but i haven't had any cravings for certain types of food that i normally don't eat. also my breasts haven't been any more tender/sore than normal and the area around my nipples is the same color it always is. of all the pregnancy symptoms i've read about the only thing i'm concerned about is being hungrier than usual
