Just need some reassuring ladies, have had 4 miscarriages never seen a heart beat with them or growth, now I'm pregnant 11 weeks today have had 3 great scans 1 at 6+1 2nd at what should of been 8 +1 but put forward a day so was 8+2 then scan at what should of been 10+2 but was measuring 10+5 heart rate 168, but I'm walking on egg shells again and terrified of something going wrong.
