okay. I'm pretty worried.

I slept with this girl in the last week of August 2014. She told me she found out she was 9 weeks pregnant (not sure how many days eg. 9 weeks X days) on 6th October and it was her exes who she slept with very end of July. Do these dates add up to you? She said it's definitely definitely not mine as she knows it is her ex's .I hope it's not mine However I think I've scared myself by using these online calculators :/. She said her due date is 5th may 2015. I think it does rule me out but it's just my paranoid nature that makes me a bit worried still.

Your reassurance would be most helpful.

Thank you
