Did an oops and previous thread got deleted.

Here I go again, I got a which is exciting . Down the street today I was still a tad in shock so I got one of the digital ones to reconfirm and give me an estimate with how far along I am. The result said 2-3 weeks which is baffling because last AF ended on the 10th of October and I have had pregnancy symptoms from late october. I took 5 tests about 3 weeks back all with negative result after having no AF. Is it possible I've skipped AF and then conceived? Unsure when I can see an OB. Could I have ovulated just before AF was due and was too early to test?

TIA
