So what did you ever find out? Mine and your situation are SO similar, even down to around the same dates. I have had 5 negative HPTS! FIVE!! However, sore boobs, bloated lower abdomen, when I eat it makes higher in my abdomen hurt, headaches, I had the morning sickness (actually 12am-4am sickness lol) for about a week back in March. Headaches, extremely exhausted, swollen ankles, weight gain all in lower abdomen region, sore gums, gas like crazy, heartburn though I have never had heartburn before, etc etc. I swear that there are even times I can feel a fluttering feeling in my lower abdomen. We arent TTC but NTNP as well. This is so crazy. Please let me know what you find out. I have to wait TWO more wks to go to the dr.
