Hi and thanks for this query. Fro the information provided, you are clearly not pregnant. Because of the different hormonal pills you have taken, your cycle which is closely controlled by hormones will clearly be messed up before becoming again regular. You will have to be patient with this. Please, the best way to protect against unwanted pregnancy is by using a contraceptive method. Consider talking to your doctor if this is something that you will like to try. Condoms, in addition to protecting against unwanted pregnancies also prevent STDs. Hope you find this helpful and informative. Wish you well. Dr. Ditah, MD
