Late Period

Hello,

i have always considered my period irregular. when i was younger (i’m 17 now) i could go a month or two without my period. now, i have it every month but it always comes at different times and i don’t have “typical” period symptoms. i have only recently been tracking my period since i have gotten into a relationship in december, but i only was tracking it in my head. i lost track after february and somewhat in march. i only kept track for two reasons, when my partner and i could be sexually active and to make sure i wasn’t pregnant. we have always had protected sex, and we use the pulling out method. we have never had sex without a condom, and i have never allowed him to cum inside of me even with a condom on. i recently got <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and logged in the times i had tracked my period and the app says i’m late, i know it’s an estimate and not 100% accurate, also i do consider my period to be irregular, but i do feel as if i haven’t had my period in awhile. recently i took valium for my anxiety and i was told it may delay my period. but to be honest even though my partner and i have had safe sex, i’m still scared in the back of my mind i could somehow be pregnant. keep in mind he’s penis has never come in contact with my vagina unless he has condom on and he has never came near my vagina. there was one instance before we had sex where he began to put the condom on the wrong way, but he didn’t actually put it on like that or pull it downward on to his penis. he hadn’t came before that and i hadn’t gotten him all fired up yet so there was really pre cum. is there still a chance i could be pregnant? should i be worried? can i induce my period to make sure i’m not pregnant? i’ve read ginger can help induce your period. i know most of this is anxiety talking, but i sure would love to hear someone else’s opinion on it.

thank you.
