Plan b failed :/

9 days ago i took plan b and now my period is due in 8 days ....the day i took plan b was the day eve told me i was fertile (I’m irregular) and today and yesterday I’ve been feeling extremely tired and exhausted and four days ago i wouodnget cramps like typical pms cramps. I’m not cramping now I’m extremely fatigue....I’m no pregnant? ALSO since it’s been more than a week from the sex and plan b i haven’t gotten any spotting or anything the only symptom is fatigue...

So i had sex September 7 (day 3 of fertility) and took plan b within 10 hours of the sex...we didn’t realize the condom was broken he said he didn’t cum in me but worried bout possible Precum...
