So Saturday night, (2 days ago) I got drunk for the first time. I’ve had alcohol before but not enough to get drunk. I know I took my BC pill at 10 which is the usual time I take it but with that being said, I ended up throwing up around 12. So I’m pretty sure I puked up the birth control. I didn’t have sex that night or the next day but I did have sex Thursday. I’m supposed to start my period this Tuesday or Wednesday. Is it possible for the alcohol to delay my period? Should I get one of those clear blue “take 5 days before your missed period” to put my mind at ease?
