Help !

Okay. So as you guys no I've been trying to conceive for about  a year now but this month we'll last month u had enough so I started taking birth control in just said forget it thing is I only took two pills and stopped because I hated the way it felt on my body. My period came April 20 it I usually comes the 17/20th if any later every month. So it came April 20 I started my pack on a Monday when I was suppose to on a Sunday. So I took the pill for Sunday and Monday on the same day and never took them again my period lasted from the 20 until the 1st wich was unusual. We'll it's about that time and it's the 22nd and I'm late I've had unprotected sex before I started my period a few days while and every day after just wondering if it is the pills delaying my period or possibly pregnacy.
