@deojames I mean, the thing is that an RE could get you pregnant if you have totally normal fertility, but that doesn’t imply that you need an RE to get pregnant.

@hal16 Just chilling! I should have linked this picture, which I love, from the developmental bio text I use in class: panel B is three intrepid pre-implantation blastocysts going on a journey through the uterus.

Today we are going to discuss a time of mystery, a time of endless possibility, a time of progesterone: the luteal phase. (Despite my clickbait title, the length of the typical luteal phase can vary from about 10 to about 16 days, and 12 days is actually the most common length. Don’t believe...

@prelude4ws Love this, wabbit! Thanks for writing it up.

@deojames After trying for three or four cycles with these numbers, I would absolutely not move straight to IVF. You have a great chance of conceiving within a perfectly normal timeframe -- it's worth playing out those odds and seeing what happens.

@kevinh So in this case, even if the implantation window was shifted earlier, the embryo itself wouldn't be ready for implantation -- ectopic pregnancy doesn't happen because implantation happens too soon in the timeline. The embryo is not ready for implantation until it reaches the blastocyst...

@j87 Just to reframe a bit here -- these kinds of studies can generally say that (very) high levels of maternal blood folate are associated with an increased risk of autism spectrum disorders in children, but not that high levels are causative. There could very easily be genetic influences...

@leviticusrocks That makes sense as a mechanism to me. I wonder if this has been observed in practice or whether it's mainly a theoretical risk.

@kevinh Is this something your provider has told you? I wasn't aware there was a connection between use of supplemental progesterone and increased risk of ectopic pregnancy, and I'm curious what the link there would be.

@rosetyler The Cleveland Clinic’s stats are a little out of line with the generally accepted numbers — usually the numbers are given that about 70% of folks have conceived by cycle 6, and and additional 15% (that is, half of the folks who remain) will conceive by cycle 12. This does give you a...

@indianwomenhealth So I definitely have to be clear that this is a "do as I say, not as I do" situation -- rationally, I know the stats, but I also get a little too goal-oriented when it comes to fertile window sex. But given that I'm a hypocrite, remember to be kind to yourself. Please don't...

@prelude4ws Duh, I should have just looked at your submitted threads...

@james6771 Ah, in the context of not having a period for a year, the LH level is a little suspicious. Typically, your LH would only be that high if you were nearly ovulating. Depending on your other test results, you may find yourself discussing PCOS with your doctor.

@savedandsanctified Based on the data, what comes out is the following hand-wavy ranking system: Top: O-2, O-3, O-1 (~equal, O-2 being perhaps slightly better) (20-30% chance) Middle: O-4, O (10-12% chance) Low: O-6, O-5, O+1 (0-5% chance) Note that these are all single-day probabilities —...

@james6771 The numbers given to the right are the normal ranges. All of your numbers fall within the normal range for the follicular phase, except that your TSH is a little low (you are a little hyperthyroid, according to this test), and your prolactin is also a little low. As far as I'm...

@michaelmorgan I know I have seen a really helpful survey over at /r/ttcafterloss where members were asked how long it took hCG to go to zero after loss, graphed by gestational age at loss. I don't recall where it was posted -- /@prelude4ws, I think it was your survey?

@giathinhpool The medication for hypothyroidism is just thyroid hormone in pill form, so there's not a huge variety of options (generally people are prescribed Synthroid/levothyroxine, which is just a pill version of the T4 thyroid hormone your body makes), and the safety profile is the same...

@emanuela And so, ironically/confusingly, "peak" on the CBADs actually means the initial rise of the surge -- it doesn't mean "peak" in the absolute sense.

@kristeen (Which is why first positive is a better predictor — they find that the initial rise of the surge is a better predictor than its peak.)

@jolyn BBT is useless for prospectively timing sex, it's true, but it's pretty useful for identifying when it's safe to stop having sex, and for knowing when you can expect a period or a positive test. Predicting when ovulation will occur isn't the whole game.
