I've downloaded a handful of <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy apps</a> since finding out - and they all range from me being 6-8 weeks. By my logic I can't be any less than 6 weeks and when I called for my first appointment they think I'm about 6 too but is there any way I can know for sure or do I just wait for my appointment on the 29th (which the waiting is killing me!)
