Does birth control make you period late?

so this is confusing.i called my doctor to start birth control. she gave me the pills on the 26th of february. I decided to take it the next day which was 2 days into ovulation. I didn't know that at the time. so this is where the problem is. I had unprotected sex two times on the 26th of feb which is the day before I started it. this month in march I was a week late then finally I got it I think. my period was 7 days late and it was never red it was first brown then pink then chunks of pink/red. and it only lasted 1 day. there was alittle red but I don't know. can the pill make you late or am I prego???
