Pregnant? HELP


So the pharmacy gave me a different birth control and my boyfriend and I had sex within the first week of having it and he went in me.. im having pregnancy symptoms but it’s not time for my period yet so I haven’t missed one. Is it in my head or is there a chance I could be? We also did it last night and that was in my ovulation window however the first time with the new BC pack it wasn’t in my window.
