Speculation on twins??

This is my second pregnancy I just took the test on new year's and got a bfp. We've been trying for a few months now and I was actually convinced it wasn't gonna happen. But I noticed a bit of a bump 3 or 4 days before my missed period. (it was due on the 26th)

Twins run in both our families but no ones had them in either side in a couple generations. I was also feeling pretty yucky before my due period too and way moodier than usual and I just chalked it up to being about to start my period.

With my first baby you couldn't even tell I was pregnant till my 8th month along. And everything just feels so early on with this one.

Any opinions?
