Could I be pregnant?

I had UPS days before my estimated ovulation day. My period is 3 days late.. Throughout the day I have very mild cramps that only last about 1 minute, which never happens until the day of my period. I have no pregnancy symptoms other than sore breasts and headaches, but that often happens around my period. I am really scared to take a HPT because I don’t want to get my hopes up. Is there a chance that I could be pregnant? ( I was on BC for years up until last March. I was having irregular periods but my last 3 periods have all started around the same time)
