12 week scan measuring 7 weeks - can't make sense of it

Hi all,

(I'll try to make this clear although my head is fried!)
I was on the pill, although I know I missed days and was scatty during lockdown. Last period started on 11th May 2020, took pill for 21 days (albeit not very well!) then started 7 day break, I had a couple of very light spotting type bleeds in that week which I thought was my period starting but it didn't come to much. On the day I should have started pill again - 7th Jne 2020 - I took a test and it was a clear positive. I would have been just 4 weeks pregnant. I have had no bleeding since.

Flash forward to today and my "12 week" scan where I was told I am only 7 weeks 5 days. By this calculation I would not have even been pregnant when I took the test. I asked the sonographer if I could have lost that baby and got pregnant again the following month and he said it would be very unlikely for that to happen with no bleeding at all. I also considered if it could be a false positive and then I got pregnant the next month because I had stopped taking the pill but I hear false positives are very rare and unlikely.

The sonographer said the baby had a good heartbeat which I saw myself and was a good/normal size for 7 weeks. He didn't seem worried and booked me in again for 5 weeks time.

But I can't make sense of the dates and have the creeping gut feeling that something is wrong. 5 weeks seems a very long wait! I should say although it wasn't planned we were thinking about trying for another baby later this year and were happy about the pregnancy when we found out.

has anyone been in a similar situation or have any ideas what could be going on?

Thank you

Bumping for you. I have nothing helpful to say but can understand your confusion and worry and hope someone has some reassurance for you.

@DefinitelyMaybeBaby what a confusing time for you! It is totally possible that your body could have absorbed the previous pregnancy and then you fell pregnant again- if they are adamant that this isn't the case I would be concerned why it wasn't measuring as it should, hope you can get some more answers in a few weeks time x

Thanks for your replies. 5 weeks feels a long time to wait, I've asked my community midwife if there is any chance of another scan in 2 weeks to check if baby has grown in line with their dates from now to then, as that would at least offer some reassurance that things seem to be progressing as expected - although I don't think I'll ever fully understand what's gone on with dates.
