I got my firsr ultrasound done on 10th jan. I got my last period on 25th November, so I'm confused how many weeks I'm pregnant. Also my ultrasound report says the sac is too small and can't say anything before next ultrasound. So, is there anything to worry!? My gyna told me to get the next scan done after 2 weeks,; but i didn't as i wanted at least 3 more weeks to be more clear. As too many scans aren't good. So, tell me when shou3i get my next scan done and is there anything to worry!?
