I took a majority of my birth control late this month. my period is now late, is this normal? had sex but no ejaculation inside me at all.

All or none: The oral contraceptive pills are low dose and designed for ALL to be taken everyday without fail to inhibit ovulation. A "majority" of pill use implies that several pills were missed in that cycle and therefore, NO protection occurs as pregnancy is always possible because of "pre cum" that occurs prior to any ejaculation during sex.
