Weird cramps?

Hi all,

I really thought we'd been successful this month, but im having strange cramping. AF is due Fri or Sat, but I'm cramping across my pubic bone? It doesnt feel at all like regular period cramps, more of a pulling than a squeezing, if that makes sense. Is there any hope I might be pregnant or should I prepare myself for a bfn?

I also have painful nipples, more discharge, & I smell different - not bad, just not like I usually smell. I've also been moody out of nowhere.

Thanks in advance!
