How common is a missed abortion / miscarriage. I had a miscarriage last year with heavy bleeding and this pregnancy threatened to miscarry at 7 weeks, I did go for a scan afterwards and everything was fine. I'm now just over 9 weeks and have had no more bleeding since but still find myself stressed that something could be wrong. I certainly feel pregnant, morning sickness has in fact got worse, I go to the toilet constantly and am always tired but I've heard that you can still have all the symptoms and yet the baby could have died. My next scan is next week, am I just being paranoid and silly?
