Please help !!

Hi i went on a trip with my boyfriend and we had unprotected sex on June 23 which were the expected dates of my period. Literally I got my period the next day but I still took a plan b.

After we had unprotected sex again on July 30th and august 1 , after he finished he put it back inside and I took my plan b the next day.

later on I had spotting days later.

I don’t know I’m scared I could be pregnant . Should I take a test ? I know this wasn’t right and we probably should have not done anything but it’s been years since I have been with anyone and I’m worried . What should I do ?
