Could I be pregnant?

Hi there,

My bf and I had sex and the condom broke and he finished in me before we realize it! We did that on Nov 13th!

I took plan b the next morning (nov 14th) at 10am. Now I just realized that the last day of ovulation for me was Nov 13th.

Today I started feeling light cramps and realized my period started...though at first it seemed brownish but then it got bright red with a clot even. Usually the day of my cycle it’s kind of light but my cramps are definitely not at bad as usual. Also, I have pcos....how likely am I to be pregnant?

Anyone know how effective plan b is during ovulation? Unsure if I was ovulating anyway seeing I have pcos...

I’ve taken plan b twice before once already in November and once in October. Similar situations!

I’d love the help and feedback!
