[ashm]

My names ashley im 18 and recently decided to become sexually active. I was on birth control for about 3 weeks but stopped because I disliked the side effects. I started my period the day after I stopped taking the pills, which was june 13th. It is now july 20th and I havent had my period again. I have had sex , but it was protected and the condom did not break or leak. I thoroughly examined it afterwards! Is my period trying to go back to the schedule it had before the pill or I should have had it on the 13th like it was last month? Could I be pregnant? Please help
