FREAKING OUT

So on March 17th I started my period and my boyfriend was in the mood I let him put his D In me for 30 seconds w out a condom he didn’t cum or anything and didn’t have a ejaculation before either! My periods are always regular (29 days exactly) and they always last 6-7 days! I started my first ever combination BC on Sunday March 18th I’m prob just paranoid! I do not have any preg symptoms what’s so ever my boobs feel normal no pain, no nausea, should I be worried or should I stop worrying.
