Birth control

ab

I’m sorry for the long post. So I started the depo shot mid April and since starting it I haven’t gotten a period. I had my next shot due on July 13 but had an immediate trip I had to attend for 10 days and had to miss it. My doctor said that I shouldn’t be more than 2 weeks late for my next shot so I had it scheduled for exactly 2 weeks on July 27th. Well my doctor had an emergency and had to reschedule for next week on the 3rd. Since then we’ve used condoms but earlier tonight after we finished we discovered that the condom broke. Do y’all think I’m okay or should I get a plan b? Sorry I’m just kinda nervous.
