Due date question

So I think I was wrong about my due date, if my last period was Oct 17 - 23 & I had sex three times within my ovulation week wouldn’t that mean I conceived within the first week of November & am 11/12 weeks currently? (I had the app Flo that predicted my period for Nov 13-19 but I can’t remember if i had it or not even though my doctor said i was 5/6 weeks when i met w her, though the app ‘glow’ said i was only 4 weeks.) Been trying to get state insurance but it’s been a real pain since I moved from NV to AZ. Can I go to planned PHood for a free testing? I seen they are asking for insurance or personal payments 😩
