I had a miscarriage 2 years ago at 8 weeks, I found out a week and a half ago that I am pregnant. I am 6 weeks and 4 days. I have been having cramps and having a lot of headaches, I haven't had any signs for 2 days now. I have a doctors appointment on the 18th Feb and they are unable to move it any closer. I am very concerned about having another miscarriage. Is there anything that anyone would advise?
