Please can someone work out how many weeks pregnant I am? Think Gp got it wrong!

This will be DC 2 so I should be a bit more knowledgeable but I can't work it out!

I was referred to hospital in December as we have been trying for a year and I have PCO. My cycles can be anything from 3 weeks to 8 weeks.

I have been having progesterone blood tests every week since 7 Dec (CD1) progesterone was very low ie around 3 until 7 Jan when it was 29 (CD31)I had some bleeding on 13 Jan so I believed period was starting and so missed the blood test on 14 Jan. Bleeding stopped after 1 day so I had blood test on 21 Jan (cd46) and it was 58.

I did a pregnancy test when I got the results (26Jan) and it came up immediately as a strong positive and clear blue digital says 3weeks+.

How pregnant am I? gp has estimated due date as 14 Oct which seems very late I would have thought end Sept?

Thanks in advance if anyone can work this out!!

No matter what, until your 12 week scan, your due date will always be based on your LMP. It does sound likely that the bleeding you just had was implantation and not a period, which would mean your LMP was 7 December although your genuine due date will be based on the assumption that CD1 was 14 days prior to ovulation, which is not the case for everyone and definitely won't be for you. I think you are right to expect the baby in September though and congratulations! I hope everything goes well.

If it was me I would calculate it from 7 Dec as due date is calculated from CD1. But it sounds as though your GP is working from the one day of bleeding you had on 13 Jan.

At this stage it doesn't matter too much though. It will be corrected when you are scanned.

When you have your booking in appointment as the midwife if you can have an early dating scan and explain about dates, with it being so variable you don't want to miss time scales for tests at 12/14 weeks. I had one because I had no periods before becoming pregnant off the pill so could have been anywhere from 8-14 when I booked in.

It's better having your scan early than late.

Thanks for replies, I was thinking 5 weeks too. Midwife called today and I spoke to her about my cycle and shes booked the scan earlier to be on the safe side- 5.5 weeks and counting!
