This Is Why I Don't Trust My Body

The ultrasound went well today. Test results, not so much.

Kiddo is still measuring on track - 6.7cm (about 2.5 inches) at 13w0d. I was thinking that measuring on track is a good indication of the health of the pregnancy, but the ultrasound tech dispelled that notion today. Apparently, because the size is so small at this point, the chance of being off on the measurement is too high to be a good indicator of the pregnancy's health.

She said they don't start to use measurements for that until about halfway through. Still, we've had consistent growth, and I'm hoping that's at least a good sign.

But test results are proving to be the bane of my existence.

We got the official results of the NK scan today. Risk of Down's is 1 in 6,600, and risk of Trisomy 13/18 is 1 in 6,800, so both of those are very good. We saw the nurse practitioner today, and she went over that table of results with us.

I didn't look at the results of the 3 individual tests that make up the results until we were in the car. The NT itself was 1.3, which we already knew was normal, and it was in the 50th percentile for results. PAPP-A was 0.90 mlU/ml and was in the 60th percentile.

Then there was the free beta HCG, which was 20.88 ng/ml, in the 5th percentile.

I know beta levels drop as the second trimester approaches, and free beta is much lower than the quant beta measured at the beginning of pregnancy. The one reference I was able to find for the difference between the two said that the free beta is generally about 1/2 of 1% of the quant beta, which would put my quant somewhere around 4,000.

The 4,000 is pretty low for this point, but I've been focusing more on the free beta results. From what I have found online (I know, shame on me for Googling), free beta results that are in the 5th percentile or lower on the NT screening have 2-3 times the risk for delivery before 37 weeks and the baby being in less than the 10th percentile for growth, and about 5 times the risk of fetal loss before 24 weeks.

So, I don't see myself relaxing much before 30 weeks.

Then after that, I got this morning's progesterone results. I'd been off of everything for 2 days. It was 17.45.

It was the optimistic nurse who called, and even she seemed rather concerned. I asked her if this happens often, and she said pretty much everyone is off of everything by 12 weeks and has a level above 20 at that point. I'm a week further along, and still not there.

She is checking with RE to see what he recommends. I may not hear back until Monday, but she explained that either way, it would just be a recommendation. Since I'm at 13 weeks, they won't continue my care, so the peri would have to be the one to prescribe it if he recommends I stay on it. She also wouldn't tell me what I should do over the weekend, but she asked me what I thought I might do, and I told her I was going to immediately restart the suppositories.

I was going to wait until Monday to call the peri, but my friend who referred me to her said to just call the peri now rather than stress all weekend, so I'm going to call her tomorrow morning. I'm going to insist on continuing the progesterone and regularly checking the levels for the duration of the pregnancy. We've approached our whole infertility experience - and this cycle in particular - with a "no regrets" attitude. I realize progesterone won't stop something bad from happening if there's something else that is a problem, but if something does go wrong and I'm not on it/don't have good levels, I know with 100% certainty that I would always have regrets about that. If she isn't willing to prescribe it, I think the RI would, so I'll go that route if need be.

From everything I've read and been told, there's no risk or adverse outcome associated with being on it in the 2nd and 3rd trimesters, Given that, it doesn' t make sense to me to not treat it and have me worry about it the whole way through. And let's face it, I would worry, big time.
