The same happened to me a few weeks back. I went to my first scan at what i thought was 13 weeks dating back to first day of last period and baby measured at 9 weeks 2 days! I fell apart as i felt something was wrong and spent days trying to work out wat was going on. I had another scan last week at what would have been 12 weeks 3 days and got put forward to 13 weeks 2 days. Although I have still lost time it does work out with hubby and I 'timings'. I spoke at length to my midwife about it as i had to go back for my bloods again and she also suggested that I may have lost a baby and conceived again straight away (i did have brown watery discharge tmi x for a couple of days 2 weeks after last period but didnt think much of it at the time). Only thing different for me was that i didnt test until i was about 7-8 weeks in my mind as didnt quite believe it so i cant be certain that i was pregnant before but it would explain not having a period inbetween. Hopefully at your next scan it will all sort itself out and make more sense for you as i know it scrambled my aready frazzled brain for a few days xxxx
same here been thinking the worst but my midwife did say that to me about losing one the falling but only has a bit of spotting for a rew day which i thought was implatation bleeding, i did tell the doctor this but he said it was nothing to worry about, so if i did lose one that would of been then, i cant wait for my scan on tue to make sure the baby is growing so keep your fingers crossed for me x x
oh honey, it can be so confusing sometimes, im expecting them to change my dates, but not by that much, i can understand why your worried.
Hopefully your private scan will shed more light on things, and hopefully you get a good sonographer who knows what they should be looking for! good luck xo
