Need to be safe!!

If I’m on birth control and i usually skip the sugar pill one month and then take it the next, which was recommended by my dr, and I had my period last month but instead of skipping it I want to have it this month. Is that safe? Ive had unprotected sex this week and I’m ending the pack this week and I’m not sure if going into the sugary pills would be safe when my body is used to going another month without my period. Is there a risk of pregnancy? Sorry this may be a stupid question but better to be safe
