Complicated...: If you had a last period Dec. 18th or 28th you could not have conceive before that. To have conceived Dec.10th your last period would've been around Nov. 28th, does that sound correct? if you are due Sept. 15 that would mean conception around Dec. 25, which is also impossible with a late Dec. period. Ultrasound is only accurate to +/- 2-3 weeks in the third trimester, so its not possible to say.
