Condom broke

I have an average 31 day cycle and I’m very irregular, sometimes I would have 36 days cycle. Last night at 2-3 am I had protected sex and one of the condoms broke (we changed condoms many times bc it wiuld get dry quickly) and right now I’m on day 12 of my cycle and I’m supposed to ovulate sometime soon this week or next week... do u guys think i should take plan B just in case? Even tho he didnt cum at the moment the condom broke. I mean there was pribably precum buthe pulled it out as soon as he felt the condom broke
