Is it normal to have 2 periods in 1 month after coming off birth control

I have a period on the 18th of and my husband went to oklahoma for vacation and bc we were so busy and the different time change I stop taking my bc pill and in still off of it well anyways I had a second period on the 31st not even 2 weeks a part is it bc I stop my taking bc pill or '' could'' there be a chance of pregnancy thanks

i think when you stop taking the pil your body is geting use to it so a second period could happen from that but maybe you should go the docs and get checked just to make sure.
