12 wk gender help

Thanks all. Wanting a girl.. my gender scan is in April! so the long wait is well, simply long. I have heard mixed views on the heart rate issue but both my boys were classic 138 and 139. Yet my second photo does look more like a boy compared to the first, so April it is to truly find out.

I don't see a nub in any of the images. The pics have to be taken on just the right imaging plane to "capture" the nub so just because the pic is a side shot doesn't necessarily mean that the nub will be seen in it. I think you still have a 50/50 chance of pink :)

Thanks lovemy4!
