Broken conform + plan B + spermicide

Li
This is my chart. The condom broke on the 30th of January. I took plan b 3 hrs later.  Also used a LITTLE spermicide.  Had my period a week after on schedule . My period is due next week but my breast aren't sore like normal. 
My period is normal. I took plan B in December, it was my first time, I was so scared for no reason. BUT January I received my period 3 days early because I took plan B in December.  please don't bash me or say that's why I need to get on birth control, I'm going next week. 
What could be my chances of pregnancy ?
