I was due on 8 weeks ago, about 2 weeks ago I thought my period was starting but I was a tiny bit of pinky coloured blood and it only lasted for a day. I have got two daughters and when I did a test to see if I was pregnant with them they were both positive straight away. I have done several tests over the last few weeks and they have all been negative. I have had horrendous headaches, I'm always hungry, I've put on a bit of weight and I have had bad abdominal pains the last couple of days, If I am not pregnant, what could be happening? Please help!
