BLOOD TEST shows 43 days pregnant - is this from conception or something else???

[bloodsuckingLOONEY]

Right, had a blood test yesterday as was unsure how far gone due to different length cycles and a light period last time. I've been told this morning that I was 43 days pregnant yesterday.

I'm always confused about how they work things, I think they normally work it from your last period but how do they work out I'm 43 days then?? How do I work out due date? (if everything ok that is, I'm having emergency scan on Friday).

Was on the pill until July and then this has been my cycles since:

CD1 - 22nd July (normal period)
32 days later....
CD1 - 23rd August (2 days of light bleeding)
25 days later....
CD1 - 17th September (light bleed off on for few days)
BFP on CD30 - 16th October

Now I'm confused about what to put in these online calculators to work out the due date??? LMP won't calculate correctly but then if I put conception date as 43 days ago, it comes up as if I'm 8 weeks pregnant and the Dr said I was 6 weeks on the phone. Totally confused, anyone able to shed any light on this?? I know I've got the scan on Friday but you know what us women are like - we want to know NOW (well, I do anyway!)

TIA

6x7=42 - therefore 43 = 6+1

I know that but how on earth do I work out my due date?? Or do I ignore online calculators and work it out manually? If so, can someone reminds me is it 40 or 42 weeks they work out EDD??? i can't remember as it's been so long!

Thanks

What happens if you put Tuesday 13th October in?

It then says 3 weeks but she said 6+1

43 days ago yesterday means day 1 was 11th September so I've just worked 40 weeks from that (is that correct?) and that works out as EDD 24th June and tbh, I'd had in my head that I was due between 20th and 27th June anyway due to different cycle lengths therefore I now think my last period WAS a period?! I'll go with 24th June I think until I have my scan. It may be all over on Friday anyway, I just wanted to know.

Thanks

Sorry, meant September... I was anticipating late June until mc last Friday: hope yours goes better!

Oh....so sorry! {{{ hugs }}}

Me too.

I've got my scan tomorrow and picked up my letter from the Dr's today. They make my EDD different to what I had worked out, got it as 16th June and also have 10th September down as LMP - last period was actually on 17th September, on 10th September I was CD19! Oh well....this I presume means I either ovulate at a funny time, there's more than 1 which is making me appear further gone or I am further gone but hormone levels are dropping as a problem.

DIGITALGIRL - your thoughts???

Update:

They couldn't see baby but could see a gestation sack and yolk sack. They said it's measuring 5+5 and they wouldn't be able to get a heartbeat until 6+ weeks. I've got another scan next Friday and they'll know for sure because if it still measures the same and no heartbeat, they'll know the baby didn't make it. Otherwise, fingers crossed, there will be a slightly bigger sack and a heartbeat. Now I've got to try and not think about it for a week otherwise I'll go mad!!! Oh....blood pressure is low and she said it will get lower (if pregnancy ok) as I get further on so I have to be very careful getting up etc - explains why I nearly passed out the other day when tidying the playroom!!

Best of luck - hope scan is OK. Keep me updated!
