Hi, I've got a few symptoms that lead me to think I could be pregnant but when I did a pregnancy test on Saturday which I thought was a day before my period was due it was negative. For about a week I kept getting nauseous, usually when I ate but it passed very quickly. I've been having very vivid dreams for about a week & I don't usually remember my dreams. Then a couple of times in the last few days I've had a really sharp pain behind my right breastbone which I thought could be heartburn. It's not constant pain & passes after about 10 minutes but it is quite painful when it hits me. I haven't tested for pregnancy again because sometimes my cycle has gone to 37 days which would be this Sunday. I just wondered if I'm right in thinking the pain behind my breastbone is heartburn? Thanks, Bex
