Possibility of a False Positive?

[PreguntonaPensativa]

So I had my prenatal paternity test done in August and I obtained the much desired he can't ve excluded as the father result. Now that I am getting closer to my due date of March 11, 2016 I am very nervous the results were incorrect. Is there any possibility that I had a false positive or is it more common to get an exclusion than an inclusion? I am really worried because my bf is really really dark and I recall my one night stand was not dark at all. My bf is always saying his babies should be dark(brown) and I am not dark so I am kind of worried about my children looking so different from him. I did my test through a lab that does testing through ddc and my results have the ddc logo on them. When i called the number on Ddc's website they told me that they could not do a prenatal blood paternity test because I am carrying twins AND I could be pregnant by two men. I dont care if I am pregnant by two men what I care to know is that I am actually carrying my partners baby. So I shoppped around by calling numbers on natera's collection sites and found a reliable lab that said that it would not matter if I am carrying twins because the dna would be in the blood no matter what. Can someone give me their opinion or experience if possible?

cheer up girl I think we are all anxious about our results only time will tell, that I've seen I've only read about two false positives everywhere that I've looked.

With my one night stand we used a condom, a quickie like less than 5 minutes, and afterwards when i stood up i felt something drip plus i was wet. I freaked out.

...With my bf we had intercourse for like for seconds manybe maximim a minute then we used a condom for another minute with no ejaculation because we were tired.

It just makes me nervous because my bf never ejaculated and the odds for precum getting me preggo...come on...then my one night stand did ejaculate even though it was supposedly inside the condom.
