Hi everyone! Iv just had a early scan should be 6 weeks. Only a gestational sac and yolk sac was seen she said I’m more 5 weeks. I’m wondering if it could be viable or not as I only had sex once and that was 4 weeks 2 days ago and given the sperm only survives for 5 days I should be 6 weeks no less? Any advice on this matter pleaseeee help (I’m on my 7th pregnancy and have one beautiful baby boy) x
