You could have just ovulated late. I normally ovulate around day 19-20 and didn’t get a positive until CD42 with my dd. When I had my HCG testing the first one was 26.

I would request a dating ultrasound around 7-8 weeks so you can make sure. They aren’t as accurate after 12 weeks. If I just went off my LMP my due date would have been like 3 weeks off.

You definitely ovulated later than you think you did and no you’re most likely not 5 weeks but you might be a week off or so.  The maximum time for a luteal phase is ~16 days.  So by 16/17 DPO you either get AF or a positive pregnancy test.  No other options really (unless you’re on meds).  If neither one of those occurs your ovulation date is wrong and you ovulated later than you thought.  OBs calculate how far along you are by assuming CD14 is O day and O day is “2 weeks” pregnant (sort of counting from the age of the egg).  So you can calculate from there.  So for example, if you ovulated on CD21 then take CD21 as 2 weeks pregnant.  You need to request a dating ultrasound since you have had irreuglar cycles.  They should be able to do an ultrasound in ~4 weeks that would be accurate for dating purposes.

I went off birth control and had a withdrawal bleed and then get pregnant without a real period.  I ovulated probably 2-3 weeks after I quit.  No issue with that.  With my second baby I charted and I actually did O on CD14 so using my LMP dates were accurate as far as dating the pregnancy.

I agree with Westwood. You likely had an LH surge, didnt’ actually ovulate, then had a second surge and ovulated then. If you got a BFP at 26dpo, a decent guess would put ovulation 10-14 days before that. So when you see a doctor, they will go by your last period, but as you ovulated late, it won’t be too accurate. 

I second asking for a dating scan to get a more accurate idea of how far along you are an a better idea of a due date.

I haven’t been in the same situation, however I have had LH surges that did not lead to me ovulating. My guess is you had a second surge later and that’s when you actually ovulated (that actually happened to me last month). What’s important is those numbers are doubling, and as you get further along, they will be able to measure and get a more acurate due date. Relying on the last menstrual period is rarely accurate for people. Easier said than done, but try not to worry! Hopefully in a couple weeks they can get you in for an internal ultrasound to ease your mind. Fingers crossed!
