What are you thoughts?

Summer

Hey ladies. I will be spending the night at my boyfriends house tomorrow and we wanna have sex. We dont have any condoms and might not have them tomorrow either. I’m on my period and I’m also on the birth control patch but it is my free week which means I take off my patch for a week so I can have my period. Tomorrow I will be on cycle day 3. I was wondering if you ladies thought this was safe not to use a condom and what you guys think the pregnancy possibility was since I’m on my period and on the patch.
