I believe I am 6w5d pregnant based on my lmp.
However, an early scan today shows I’m only about 4 and a half weeks. I got a positive test almost 3 weeks ago and I know the date of conception was the 1st February as that is the only day I saw my partner this cycle due to working away.

How can I only be 4 and a half weeks if I know when I dtd and I got my first positive test so long ago. Thanks in advance

Have you been testing for when you ovulate? It is possible for sperm to live up to 6 days so even though you only had sex once you might not have conceived until 6 days later! Also some embryos take longer to implant - some don't implant until 12 days post ovulation - so if you take both those factors together it could make you a lot earlier in your pregnancy than you think?
Have you had your HCG levels tested?

Thank You. No they’ve not tested hcg levels. They just said to go back in 12 days for a rescan. The only way I’ve tested hcg was with the clearblue digital which changed from 1-2 weeks (2 weeks ago) to 2-3 weeks (last week)

I would maybe test again to see if it will
Now show 3+ on the Clearblue? (But I'm a compulsive tester for everything 😬!)
If you can't wait 12 days I would see about getting private hcg tests done? They are usually only around £50 a time and space them out over a couple of days to see if your hcg is doubling normally?

I’ll look into that thank you. I did do another digital yesterday which still showed 2-3 but you could also see the 3+ very faintly. Not sure if that was supposed to happen though

That's odd I've never seen that.....

If you're sure of your dates then tbh I wouldn't be feeling too confident that the pregnancy will progress. I really hope everything works out fine for you though.

What did they see to date you at 4.5 weeks? Did they say they saw a gestational sac but no foetal pole or something like that?

So sorry op but this doesn’t sound good, could you book an earlier scan?

Doctors calculate your pregnancy date based on day of the cycle you conceived, so day 1 of your period. So it makes sense you would be six weeks along instead of your calculated 4 as ovulation is typically on cycle day 14.
Hope this helps.
