Hi Welcome to HEALTHCARE MAGIC..

I have gone through your query and can understand your concern...

First of all most important is that a women doesn't get pregnant before last menestrual period(LMP). Normally a women concieves on an average 2weeks after LMP. So you are not pregnant from your ex husband or ex boyfriend.
Your LMP should be 24th September & therefore you should be 10-11 week pregnant on december 11 according to your LMP. This also relates with the ultrasound. Therefore your are pregnant with your boyfriend both from LMP & ultrasound tests.
However you could do a DNA paternity test to confirm, Which is not neccesary as per my opinion.

Refer to a gynaecologist

Hope this information helps
