2WW: HCG and LH daily testing, daily BBT (OvuSense), Mira charts

[LucyCL]

This is my second cycle after CP. Today is CD 22 and I just got my peak last night. So today is the LH peak day and tomorrow will be the O day.
However Mira says today is the O day and there is only 1 day difference. To be honest, I don't know when my body will ovulate so OvuSense will help me to figure out the exact date. BBT rises after ovulation.

I will update my LH and HCG tests, BBT (OvuSense) and Mira charts every day from today until I get my AF/BFP. Occasionally I will also share my RHR chart here.
For my last two BFPs, I got a super super faint line on 10 dpo.

Tomorrow will be the O day/1 dpo. Happy testing!

CD23 The O day/1 dpo
BBT rose from the mini dip. I am still not sure about the BBT dip before the O day.
Will start testing HCG from tomorrow.

Pdg is 4.8 ug/ml. When it is 5 or above 5, that usually means Ovulation has occurred.

CD 23 The O day/1 dpo afternoon
Tomorrow morning I expect to see a rise in BBT and pdg to rise above 5 ug/ml to confirm ovulation.

CD24 1/2 dpo
I wonder if the day when I got BBT dip was the O day...

CD25 2/3 dpo

CD26 3/4 dpo
My SMU was diluted but OvuSense thinks I am in the ovulation window?!

CD26 3/4 dpo evening
LH strip got darker, my pdg shot up which confirms ovulation!

CD27 4 dpo
OvuSense finally confirmed that 2/7/24 was my O day which matches the day after my LH surge. That makes today officially 4 dpo.

CD28 5 dpo
The hcg test strip I used yesterday now has an indent and it happened on 9 dpo last cycle. I find them really evil. I will not be fooled anymore.
If not BFP this cycle, then having sex every day is what I will do for the future cycles.

CD29 6dpo
Once again Mira has successfully made me worried about having low progesterone and estrogen so I am determined to do a female hormone blood test tomorrow morning to make sure everything is fine.

CD30 7dpo
It is good that I am doing a female hormone blood test this morning to verify if Mira is reflecting true data. Will share the blood test result later this afternoon/evening.

Ooh, I’m interested in mira so keep to hear if your blood test matches!

The blood test result is back.
My progesterone level is 24.4 nmol/l which is 7.7 ng/ml
Here is what I have found online:

"If your progesterone level is high (above 5 ng/ml) this confirms that you have indeed ovulated and entered the luteal phase, the second half of the menstrual cycle."

"Ideally, your "day 21" peak luteal progesterone levels should be 10ng/ml or higher."

"Progesterone level required for pregnancy:
≥ 5.6 ng/ml (18 nmol/l): According to a recent scientific study"

My analysis

The cycle when I had CP: I didn't take any extra vitamins apart from the prenatal vitamins

The cycle after CP: I took the prenatal vitamins with vitamin B6, vitamin E, Zinc, Magnesium and Vitamin C every day . My progesterone level was 59.4 nmol/L which was 18.68 ng/ml on 7 dpo.

The second cycle after CP: I take the prenatal vitamins and vitamin C every day.
My progesterone level is 24.4 nmol/l which is 7.7 ng/ml on 7 dpo

My estrogen levels for two cycles are within the normal range. I also ovulated both cycles.

In conclusion ...
Low progesterone is very likely to be the cause of my CP.
In that case, I will resume taking vitamin B6, vitamin E, Zinc, Magnesium from today.

Although pdg figures are very low on Mira however it is good to see if a person has low progesterone based on pdg. It could act as a warning. 😅

But I do not think the figures of e3g from Mira reflect the true level of Oestradiol.

Have you had your vit d tested ?
And prolactin?
And iron / feretin ?

I took the ultimate performance blood test on 28/6/24 from Medichecks. Yes, my vitamin D level was within normal range. I had High fettitin level and my iron level was within normal range. My prolactin level was also within normal range. That is the most recent blood test I've done to make sure the second cycle after CP is normal.

Are they important factors of potential MCs? Just wonder.

Theres a vit d and miscarriage link 4 some

Tommys baby charity knw about that.

Also gd feretin is often needed 4 conception and pregnancy.

If prolactin is high - too high - progesterone can be low

Wow, I only knew about vitamin D.
Thank you so much for the insight!

The book
It starts with an egg
Is good

My core BBT dropped with a rise in e3g and a drop in pdg. This is called Secondary Estrogen Surge. I still think Implantation dip is a myth!
Here is what I found:

"There's a big spike in estrogen at mid-cycle corresponding with the fertile window, and then there's a smaller bump around mid-luteal phase. That estrogen is also made by the corpus luteum, and the CL generally makes either estrogen or progesterone at a given time, so the mid-luteal-phase estrogen surge is associated with a brief drop in progesterone. This is the cause of mid-LP spotting, and often of a brief temp dip.

It's not a bad sign, overall it means your ovaries are doing their ovary thing but it doesn't mean either that you conceived or didn't (as you know, since it happens every month!)."

So I am not worried at all. My body functions normally! 😃

CD32 9 dpo
As expected, BBT went back up after the secondary estrogen surge.
My luteal phase usually lasts for 11/12 days so I only have to wait 2 or 3 days until I know the outcome.

CD33 10 dpo
My BBT has risen again this morning based on my oral BBT, wrist temperature and OvuSense. Progesterone is the heat inducing hormones so it also makes sense for pdg to increase. However instead there is a decrease in pdg based on Mira.
So, I don't know.

About the triphasic chart which I mentioned a few days ago, I believe you can see it in my oral BBT chart.
My baseline BBT: 36.4
After Ovulation: 36.9
The second BBT rise: above 37

You are likely to see it on the BFP BBT charts. HOWEVER I still think it is too early to tell as today is only 10 dpo for me. The only thing I am certain is that I don't have a short luteal phase
Short luteal phase lasts less than 10 days.

I have 2 more days to wait. That is good enough for me!

CD33 10 dpo
I used First response and it was negative as expected. If my BBT still stays elevated, I will take another one tomorrow morning.

CD34 11 dpo
BBT dropped, still above baseline. LH has risen which is really interesting. LH was below 10 on the same dpo last cycle.
I got my AF on 13 dpo last cycle so I would have to wait for one or two more days.
It is nice to know when things are coming to an end. 😁

Update: Well, I know you are not supposed to measure BBT anytime but I did measure it at 16:00 and it was 36.61 degrees. So, I expect to have AF tomorrow. Cannot wait to start the third cycle after CP!

This time I'd expect to have a normal one, like ovulating a bit earlier and shorter cycle length. My cycles used to last for 27 -32 days before MCs. The previous 2 cycles plus this one have been really long for me, 34 days!

I don't expect to see light spotting in the new cycle. Let's hope it was just one off thing because the second cycle after CP was still slightly affected by CP. My body failed to ovulate for 4 times and I had 11 days of "High" from the CBFM which was not normal at all.

I am now sharing the wrist temperature and RHR charts to conclude the end of the 2WW of the second cycle after CP.
Fingers crossed for tomorrow!
