CD24 is my guess

@Rose120:  Do you remember why you discarded the temperature on CD30?  That would actually be my guess, although that would only make it 9dpo when you tested positive.  Otherwise, I would say CD24.  FF is definitely not right!!

Using May 10th as your ovulation date (which makes sense using an ovulation calculator with a long cycle date) that would put your due date around January 31st.  Make sure you tell them that you are unsure about your dates so that they will do an early (dating) ultrasound.

My doctor based my due date on my last period…so maybe you should do the same?  Then, if after your first ultrasound, they think the date needs to be altered, they will.  Honestly, I think it’s too hard to pinpoint the exact date, otherwise.

Due Dates are calculated either by adding 280 days to the day of a last period OR 266 days to the date of ovulation (sometimes also worded as conception).  If you knew your exact date of conception or ovulation, that would be the most accurate since some women have 28 day cycles and some have 60+.  If you have a cycle that falls in the “typical” range (27ish to 32ish days) they will just go by your last period.  Generally they use this (LMP) anyways because most women have no true idea when they ovulated or an exact conception date (and then adjust later after ultra sound).  However, due to the OP’s long cycles, it is probable that the due date is a little later than going by LMP.

 

As for the first appointment, it will depend on your area it will likely be one of two things:

1. Pee test to confirm pregnancy (possibly followed by blood test if it’s negative), height, weight, blood pressure check.

2. All of #1, plus a nice long talk with a nurse or other staff to get a medical history and explain a lot of tests to you.  You will be given blood work to get done (if they do not have a lab) and the option for a Cystic Fibrous Carrier Test (optional, and expensive if your insurance does not cover).  You might also get some books, checklists with safe meds, unsafe foods, and suggested snacks (to get those extra calories).  You will also be able to ask any questions you might have. 

Either way, you will probably schedule (if you haven’t) an appointment with your doctor (or a doctor if you have a rotating style OBGYN practice) for about 2 weeks from then. First appointment is usually information type stuff or just measuring.

The first ultrasound will be around 12 weeks (if you choose to do either screening/NT scan) or earlier if you are very unsure about dates or there are any red flags.  I got one at about 5.5 weeks because I had super painful spikes in lower abdomen and they wanted to make sure everything is okay.

Hope this helps!

I think CD16.  The dip on CD24 could be implantation.  Do you have a typical O day?

Based on an O date of May 2nd, the due date is January 23rd. Congratulations again 🙂

I think cd28, but that is a tough chart to read.  I’m only looking at temps since your cm reporting isn’t consistent I don’t think much can be read there.

Congratulations!!!

I’m torn between 24 and 16, but I definitely don’t think it was CD9. My personal guess is 16, because the dip would be logical for an implantation dip.

 

Try changing your “method” on FF and see if it is any different. They have 4 different calculation methods.

i’m inclined to go with @chastenet on this one. but dang, your chart is tough to read! congrats on the BFP! If it was CD 28, then your due date would be Feb 4th.

Sorry you haven’t received any diffinitive answers, but you’ll know more soon! Hoping it goes by quickly!

@Rose120:  On the left hand side of your home screen, there is something that says settings. On the right side of that page, there is something that says “charting settings.” There you can change all the methods; theres a popup that explains all the kinds. Also, you can discard your temp on maybe CD9 or 10 or both? Mess around with discarding some of those and see what happens. The dotted crosshairs mean that even FF is doubting it’s calculated O date (I got some dotted crosshairs this cycle too..ironically on CD9 haha)
