This is my third pregnancy last year I had two missed miscarriage both at 9 weeks which ended with DandC. They did lots of blood test back then and found out I have blood clotting disorder and also mthr. Now Im taking heparin injection and aspirin every day and this pregnancy I felt a bit different than the previous ones. Before never had nausea but know I felt it a bit, I couldnt eat certain food or coffee, I had back pain and I was tired. I had a scan 2 days ago, but it was only a nurse she said its ok, their is a hb and bye bye. But today all my symptoms are gone... I will have another scan 3 weeks time but I am so worried I could just cry. But is it normal? All symptoms can just go???
