If you're pregnant you won't get your period, and my understanding is you shouldn't be on birth control pills if you are pregnant.

Oh, as to if you will get your period the first month after taking the pill, you should. However, it takes a while for the pill to take effect. The doctor should have explained this to you before you started, as you should use a secondary form of birth control for, at least, the first few weeks. Runs...

TO ANNONYMOUS: I am on birth control and i try not to miss any pills but everytime i do, it messes up my cycle and i start my period no matter if its in the middle of my birth control. This month, i missed 2 pills and nothing happened. I have symptoms that are all pointing towards me being pregnant. I called my doctor and shes the type that talks fast and is annoyed when you ask too many questions so i told her like 2 of my symptoms and she cut me off and said i wouldnt be showing signs if i were pregnant...but i didnt have time to tell her that its been going on for 2 weeks. She said not to stop my birth control so i havent. I read the birth control papers and it says if you think you may be pregnant stop the pill immediately and talk to your doctor bc it may cause birth defects. I was wondering the same thing: What if I am pregnant, will i still get a period when i start the sugar pills? Birth control, no matter what, makes your body think its pregnant and when you take the sugar pills it makes your body think its having a miscarriage...and thats why you have a controlled period. Now, i know you can have a period and it may be irregular and that can sometimes indicate being pregnant... i start my sugar pills tomorrow so im nervous. ive been waiting to find out for 23 days!!! if i am pregnant i hope my baby doesnt have any birth defects bc my stupid doctor is a bitch and wont let me talk!! lol wish me good luck! (fingers crossed) X X good luck to you, annonymous!! TO RUNS WITH SCISSORS: if you dont have anything helpful to answer or just think your being a smartass then stfu, seriously! she didnt IMPLY that she was and you even stated that she said "IF IM PREGNANT"
