I went to the doc recently I was 16w5days by lmp and ultrasound. Am I pregnant from the oct 14th or from my spouse now please help!

Wait until the baby is born and do a DNA test... you can't possible know for absolute certain until then. Until then neither of them will know which is the lucky daddy.

Well when I went to the doctor he said first ultrasound wld have said I was 12 weeks not 7. And that ultrasound wld have given me a much earlier due date.

It is hard to say at this point, again, to be 100 percent sure, you will need to do a DNA test
