so me and my boyfriend have sex very often we use condoms only sometimes but one day i forgot to take my birth control and i usually take it at abt 9pm and took it at like 11am or 12pm the next morning. i am now three days late for my period. i dont know if its because im pregnant or if its bc i had sex the day it was supposed to fome and its just delaying my period? i dont know im so scared please tell me what you think. i took two tests and they came back negative.
