Normally my bbt doesn't go to 98° but as of yesterday I was hit with a terrible cold so that might be it, but last night was terrible I thought I was going to puke (which I normally don't) so I popped a zofran just in case (I had some extra from my pregnancy) anywho could this spike in temp mean that I'm pregnant?
