Pregnancy chances ? Cross posted

So my insurance lapsed in February and I ran out of birth control about 2 weeks ago. My period was the 10th-12th, normal timeframe but it’s usually exactly 5 days. Well then last week on Wednesday I had another period, which I looked up and everything I read said it was normal from stopping birth control. That ended Friday night/Saturday morning . Last night my boyfriend and i had sex with a condom, and right during the finale it broke. My next period, of normal, is due in a week. but with the withdrawal last week and then stopping my birth control which can mess with your period by itself. So I’m wondering what the chances are I could get pregnant? We’re normally careful, my money was just tight last month. And I don’t want to take Plan B because I used it once a few years back when the condom came off and I had horrible side effects. I couldn’t eat, I was constantly nauseous, I had cramps 5x worse than any period I’ve had.

I have cross posted this, I can’t remember which groups are active. Sorry if you see it a lot.
