Thanks for taking the time to read this. So I thought I was 6w3d. yesterday had cramping and brown spotting. eventually got doctor to agree to a scan which I had today. It was a transvaginal scan that was carried out and basically she said that the gestational sac measures 5mm which makes me 5 weeks pregnant (nothing else there) and that it is far too early to tell anything else and a further scan booked for 20th April. Ok so on the positive note you could think well at 5 weeks the cramping, possible implantation spotting is explained and also the lack of pregnancy symptoms all make sense. But what doesn't make sense to me is that it was 19 days ago when I got my ............. so surely the maths say that I'm more than 5 weeks. My LMP was 24th Feb. Ovulated around 7th March. Very faint positive 21st March.............. I just don't get it. Please give me your words of wisdom - good or bad............... Mollie would have been 18 months old today so emotional anyway.
