I'm so with you!! I feel like every twitch and twinge is under investigation-- the hyper-awareness is enlightening sort of but nervewracking at the same time!! It's a relief to know "something" is going on because that's better than "nothing", but figuring out what those somethings are is making me crazy!!
here's where i stand:
+opk last wed/thurs, light spotting last thurs/fri, horrible metallic taste in mouth on sunday, and 'constant' nausea since mon/tues, vomiting since yesterday... NO CRAMPS THOUGH.. some weird sensation more like a stabbing/sharp pain- but not normal squeezing cramp... BFN on hpt- i know it's probably too early but i have a patience problem :O)
nausea and vomiting are actually my first symptom of AF- usually about 3-4 days before bleeding (oh what fun!!!) and cramping is usually 1-2 days before AF... I starting vomiting about 7 days prior to my missed period with DS (lasted until the day i gave birth!!) my second pregnancy signs were decrease in milk supply/fatigue/vomiting... I'm so lost because my PMS signs seem to mimic my previous pregnancies, but the timeline is off...
this next several days will be nothing short of torture :o) whether i'm met with BFP or AF, at least it's an answer!!!!
good luck to you and here's hoping your cramping and temps are signs of good things to come!!
