Oh mel, so sorry :( . But wait, it was early to test, right? What dpo are you? Try again Thursday, wasn't it?
That's an interesting one about trypsin brown .. I hadn't heard about it, so I went digging. I found this excerpt interesting:
In the study, researchers found that human embryos typically produce a chemical called trypsin, which signals the womb to prepare its lining for implantation.
But in embryos with significant genetic abnormalities, this chemical signal was altered, and it produced a stress response in the womb that could make implantation unlikely, the researchers said. [9 Conditions That Pregnancy May Bring]
The researchers likened this process to an "entrance exam" set by the womb — an embryo needs to pass this test in order to implant.
But sometimes, the womb may make this exam too difficult or too easy, which could lead to the rejection of healthy embryos, or the implantation of embryos with development problems, the researchers said.
This last bit is interesting to those with the 'unfussy womb' thoughts.
I've not had the shakes from any combo of meds I've been on brown but I do get them if my blood sugar gets low - have you had that tested, just a thought? Seeing an endo is a good idea too, there may be other reasons too. How long has it been going on, can you tie it in with anything you started around that time? It could be your system is sensitive to something you're taking, or combination of them?
