I completely missed my period last week. Hoping I was pregnant....I took 5 different test and they all said negative...

I'm in my fertile window now. I've been checking my cervix. And it's high and open. And Hubby and I have been doing the Baby Dance everyday so far since my fertile window started. This is also our first time trying preseed!! And ever since I missed my period...I've been sick to my stomach and nauseous. And ever so often cramping in my ovaries. I am bloated. But not bad. I figured maybe AF was coming. But these aren't my typical AF symptoms. Anyone have any suggestions or opinions ??

Btw...we are going in 8 months ttc for #1!
