6wks but gestation sack only measuring 4wks1d

[tami333]

hello there, i had a silent miscarriage in march (at 9wks) and am now pregnant again. My LMP was 24april with an average cycle length of 30days. I should be around 6wks but had my first u/s today and the gestation sack only measures 4wks1d. A pregnancy test taken on 21may showed a very very faint positive. So if Im really only 4wks conception mustve occured AFTER the pos. preg. test - so since theres not much logic to this i was wondering if i have to prepare myself for another miscarriage or blighted ovum? Has anybody had the same thing happening to them? Is it possible that due to lower hcg levels the growth in the early stages is slowed down but the pregnancy will still progress normally?
Thanks for your help

maybe your dates are off and you got a faint positive because the HCG levels from the previous pregnancy where still going down.

if you are in fact you are 4 weeks 1 day you may have concieved on may 26 or near that date. maybe from may 22 - may 28

i really hope that that's what happend and that you have a healthy pregnancy.

i guess you wont really know until your next u/s, you should have a follow up ultrasound in about 2 weeks and your hcg levels cheked to see if they are rising

good luck

Maybe your dates off since the mc...keep the faith....i would keep track of levels of hcg and u/s if doc will repeat every week.......
