Early scan worried about size

[MrsKate]

Hi there i had a early ultrasound scan today to rule out ectopic due to pain . My lmp was 7th jan but my cycle is so irregular last cycle was 35 days . Scan today shows gestational sac measuring 4.7 mm and the early signs of yolk sac they are dating me as 5 weeks but i only bd once this month and i sure about my dates i should be 6 weeks . Im still so worried i wish i could calm down . Ive had prev mc in 2009

[Sad] you must be really anxious. I have nothing constructive to say which will shed any light on it, but just wanted to say good luck. They are always wrong about things aren't they, and only a week out so hopefully it will all still go well - also maybe some are just smaller than others at that stage but it still works out fine? Hope so x
