Dates confusing at ultrasounds?!
so I just wanted to see if anyone could maybe shine some light on something. I fell Pregnant and due to previous miscarriages I had a private scan at around 8 weeks. By the dates of my last period I would be exactly 8w2days. Had the scan and surely enough I was exactly that. Anyways at 11w3day I had awful cramps and really wanted to know everything was ok so again went for a private scan. They was adamant I was 12w2days! I said no way I’m 11w2days. Says theyre completely positive I am over 12 weeks. How is this possible?!? How can I measure exactly what I was at 8w2d and then exactly 3 weeks a day later at what I should have been 11w2 be 12w2????
have my nhs free one on Wednesday so interested to see what he/she measures but can anyone maybe help me out here?
Thanks a bunch x
