For the last couple of months I have been feelin light headed, nausea, faint, extremely tired all the time even though I've slept loads, pains in my back, weird cravings and been eating more than usual. I took a pregnancy test end of March, the first test didn't work properly and the second was a negative. I'm booked in the doctors in two weeks but it's just been on my find a lot lately. I just wondered if anyone could help me?
