I have recently been to the doctors as found out I'm pregnant. I'm about 7 weeks and the doctor booked me in to a midwife next week. I can't shake the feeling that something is wrong and how do I know the baby is still alive and growing normally? This is my first baby and I'm terrified, the doctor didn't confirm I was pregnant but took my word for it, I had 4 positive pregnancy tests. What should I do?
