I know it's early!

I'm so positive that I'm pregnant... I'm only two weeks past my period but my BB's hurt my nips feel like they're sunburnt when I touch them, I've been sleeping heaps and nausea (even vomitted once), indigestion, loss of appetite and then suddenly very hungry... Also I always get two lines on a ovulation test (due to pcos) and when I took one yesterday it was a clear negative!!!
